FWIW, I am getting surprisingly good results on a 50" Micromax
I ordered it for the heck of it since it cost just a tad more than known brand 32"- And pleased to say that the contrast /viewing angles are as good as the Samsung in the living room
Can't comment on the longevity
Also, Vu is supposed to be a better brand than Micromax
As for the smart bit, you are better off with OSMC running on a Rpi2 compared to the in-built smartness of any smart TV
Suggest you go to a store and compare the Vu back-to back with others
