my view on smart tvs is, errr, dont get a non android tv one. my samsung 2013 smart tvs are pretty dumb now with apps disabled. and they have become very slow. android tv is great, but the sony tv android chips arent all that fast, and can be slow to start sometimes (tvs dont usually turn off, just the screen, so first boot or full reboot its slow, other times its in the app where you left it).
If i was deciding between two very similar tvs and the price for a android tv vs a non android tv was $200 or there abouts, i would spend the extra $200, but no more than that.
having one remote with everything built in is nice, but you cant upgrade the cpu/memory and in a few years its going to feel sluggish most likely.
