46ES7500M - Is it worth it?

[Tahvok]

Hey guys! I'm new here.

So here's the thing-
I have a d6600 tv which broke up.

My warranty guys told me that this TV is not available anymore in my country, so they offered me to take the ES6200:

Now, it's kinda the same as my current TV, just the newer series. So I asked them if I could add some money and take a better one.
Currently I'm thinking on taking the ES7500 one.

It will cost me some money, but it's OK considering the price I've paid for the d6600..

So what do you think about my choice?
Is there any known problems in this model?
Is there any other model you would offer me instead?

Thanks in advance!
