Web browsers aren't very good on the smart tvs, due to cumbersome interface, lack of flash, etc.
Instead the selection of smart tv internet apps are whats important.
I find Panasonic Smart TVs have a good selection including for movies: Vudu (HD & 3D support), Amazon Instant Video, Netflix
Samsung Smart TVs have a similar selection of apps but lack Amazon Instant Video which purportedly has better video quality than Netflix streaming video.
