Which 50" TV max. budget £900

[edition]

As per title I'm after buying a new tv that will be wall mounted. I'm not too bother about speaker quality as that will go through my current setup.

I've seen a Samsung 7000 series and a Panasonic 750b. I'm leaning on going for the Samsung, am I picking the right one and are there any im missing?!?

Would prefer to buy from John Lewis.

Any help would be much appreciated.
