I have used both Vu Premium Android....43 inches both
Earlier I bought Vu Premium Android 2019 variant and on using Fire TV Stick 4K with it, I used to get green/pink flickers at bottom of screen on playing Dolby Vision Content on Netflix, they tried manually updating softwares but the issue was not resolved, then they replaced my complete TV with new one but the problem existed and they even checked this thing with their own Fire TV Stick 4k by plugging it onto my TV.
Finally they agreed to replace that TV with the VU Cinema 43 inches, the major difference between both is the speakers, while the first one had 20W speakers and new Vu Premium Android 2020 variant has 24W, the cinema TV has 40W speakers so that is a big benefit.
PQ wise both are good, while Vu Premium 43 had a VA Panel, Vu Cinema 43 has an IPS panel but nothing major difference in both of them, moreover Vu Cinema has 100 nits of more brightness.
The two areas where I found VU Premium Android better is its inbuilt media player was really good, easily handled external 4K video files while Vu Cinema Media player lags while playing external 4K videos using Hard Disk/USB, still I installed VLC and the videos are working great.
Secondly in Fire TV stick when I kept Match Frame Rate to On, the premium android used to play Prime Videos at 24Hz,25Hz or 30 Hz, but now in Cinema Tv , it doesn't switches the Frame Rate and continues playing at 60Hz, need to find out why it happens.
Still because of sound and Dolby Vision playing perfectly I find Vu Cinema better.
