Not sure about this Sony TV but assuming it's close to
this one, the Samsung one is better.
You could also look at the JU7100 which is basically the same thing at the JU7500 but without the curve.
The best current TV you can buy for this size right now would be
this one, this year's models from Samsung are really good.
The other recommendation would be this one, but I'm not sure about Vizio being easily obtainable on Europe. Here for example we don't have Vizio.
If I were you I'd just buy
this or
this depending which you prefer curved or not. It's slightly above 1K GBP but it's the best you can buy so it's worth it.
