Samsung JU7000: Full review
It is a mid-range TV Samsung, below the "JS" series. This model is also available with curved screen: JU7500. It is a suitable TV to watch TV especially in front, with good contrast.
It has active 3D and the Smart TV is one of the best 2015. It is recommended for gamers, for its low input lag.

Sony X8508C: Full review
It is the second step of Sony for 2015, behind X9005C. This TV has a good 2D image quality, the VA panel is ideal for dark environments without losing contrast and especially if we will not see it from the side, where it loses a bit of quality quickly.
The SmartTV is correct, but far from the best of 2015. We expect an evolution of Android TV soon. It also includes active 3D. The input lag is about 40ms, good to play, but too much for true gamers.

LG UF850V: Full review
Like the other models this is also the second step of the brand UF850V 2015. LG is a good TV with IPS panel: wide viewing angle, good brightness and colors but the contrast is less than the models with VA panel. A TV highly recommended for the whole family, but not if we watch films in the dark or in a dimly lit room.
It includes passive 3D and the Smart TV is the evolution of the 2014 model, the webOS 2.0 is considered the best Smart 2015 with the Magic Control. The input lag is about 45ms, too much for gamers.

Panasonic CX700B: Full review
This TV is the midrange of Panasonic in 2015. It is not the best or the second best TV Panasonic 4K 2015, is behind CX800E and CX900. While waiting to go on sale this TV can compete with the rest of televisions here compared with a price considerably lower. The best of Panasonic CX700B is the 2D image quality, with good contrast and good brightness.
The CX700B Panasonic has 3D and Smart: My Home Screen is not as good as LG and Samsung platforms. Inputlag values below 35ms make it a good choice for gamers, but the motion blur doesn't work perfectly.

Approximate prices 55 inches:
  • Samsung JU7000:  £1,700 
  • Sony X8508C: £1,800 
  • LG UF850V: £1,400 currys
  • Panasonic CX700: £1,350 Amazon
Our conclusion on these TV models 4K 2015 is quite clear: There aren't cheap televisions, and we believe that should work well in all conditions:
We believe that the LG UF850V is not recommended because of its low contrast, typical of IPS panels and only recommend it as a family TV with great extras, good 3D, Best Smart ...

Sony was characterized last year as the best brand for gamers, but the 2015 models have more input lag than Samsung. The Sony X8508C has great image quality, but its price is too high compared to other brands models reviewed  here.

The Samsung JU7000 is a complete TV with good image, good extras, low inputlag, ... in short a TV highly recommended, including its price a little tighter than the Sony. We do not recommend this TV if you're going to watch TV forever from the side.

On the other hand we have the Panasonic CX700B which costs about 300-500 € less than other models and remains almost the same 2D image quality, but loses extras, and worse Smart. We hope time to market of the CX800, but is also a TV highly recommended if you do not give importance to the extras, one of the best value for money of 2015.

We believe that these models are a good choice if we want a very good TV without paying a small fortune.

Sony Smart TV: AndroidTV 2015 review

The Sony system for connecting to Internet is the Android TV, its Smart platform to access applications and navigate the Internet. Sony completely changes its SEM for Android-based model.
Not everything is the Smart TV:
The best of Android Sony TV is the compatibility with different devices and the voice command function. The interface is not as simple (minimal) as the LG webOS.
Andorid seem to fight for make the jump to OS of the TV, but it's still a young system and is not up to others like LG.
The remote control is: Touchpad remote control but not as functional as pointers controls, best for access to the menus. Perhaps it is better to use the smartphone as a remote control.

In conclusion we can say that we expect a lot of Android in the future, especially in applications, but the interface is far behind its competitors. The pointer control would also be a good help. Despite this, which will be the limits of Google OS TV?. Video Sony Android TV

Panasonic Smart TV 2015: My Home Screen 2.0 Our opinion

My Home Screen 2.0 is the 2015 Panasonic Smart platform, through this platform can access Internet content and applications. This system improves using Panasonicy 2015 models are based on FireFox.
Not everything is the Smart TV:
My Home Screen 2.0 is easy to use thanks to its graphic interface, in addition to using open source to promote their development. It is a quick system but lacks time applications. The browser is difficult to use without a mouse and keyboard. The best of my Home Screen 2.0 is the possibility to configure the home screen according to your preferences.

The remote touchpad also improves, expanding the touch surface that allows better control of the mouse .. (confirmar modelo??)

We can conclude that the Smart system works well, it is quite fast but this isn't the best of 2015. Video Panasonic My Home Screen 2.0

LG Smart 2015: webOS 2.0 (the best in 2015)

The Smart Platform allows you to connect to the Internet through the TV, provides access to applications and browse the Internet. Each brand has its own system SmatTV, in this case 2015 LG introduced the webOS 2.0, the evolution of the system 2014 that it was quite good.
Not everything is the Smart TV:
The WebOS of LG 2015 improves the 2014 system, especially in speed. The webOS is simple and intuitive, so that other brands have copied the format (or have reached the same conclusion). The icons appear at the bottom and allows moving from one application to another page without closing the previous one. LG webOS system manages to integrate the platform as a part of the TV.

The remote control works as a pointer: "Magic Remote", this works very well for large icons, something more difficult to point to small targets.

LG greatly improved its system in 2014 and in 2015 doesn't need a revolution, just improve the speed, one of the most criticized aspects last year. Our conclusion is that this is probably the best Smart 2015. Video Smart webOS

Samsung Smart TV 2015: our opinion (Tizen)

The Smart TV is the platform that allows you to access the Internet with the TV (must be connected to the router via Wi-Fi or cable). The Smart TV is important, but shouldn't be the determining factor.
The Samsung Smart TV 2015 TIZEN improving the previous system: easier and faster. The system works really well and it is easy to use, especially with the remote Smart Control. The Quad-Core / Octa-Core processor provides good response time and the OS works well.

I am hidden

Smart screen appears at the bottom as an icon, not full screen as the system in 2014, which makes it easy to watch TV while accessing applications.

In terms of applications available it is not yet at the level of 2014 but we expect Tizen more complete soon. It features web browser.

Conclusion (verdict):
Our opinion about the Panasonic CX680B is not bad, it is a mid-range TV with 4K resolution, without 3D. The SmartTV works well, but isn't excellent. Our opinion is that it is a model that you should not buy without looking before the CX700B, with a very similar price, even cheaper in some stores, and improving 800Hz, so the weakness of the CX680B is corrected. Our advice is to check the model Panasonic CX700B before buying this TV.
