Need advice on two tv models.

Hi,
As the title says i'm looking for some advice on these two models Sony x800e and Sony x900e. I have been reading so many reviews and watching so many videos on these two models and i can't decide if it's worth paying double the price of x800e to get the x900e, also i would be looking at 49 or 55 inch models.
Any advice would be really appreciated.
Thanks in advance.

I should also add that the use for this will be mainly gaming/netflix.
