Drunk bought at 43" TCL series 5 last week. I loved my old Vizio (and it still works after having it for about 11 years) but going from 32" to 43" is appropriate for my living room size (which is fairly small) and honestly it was about time. Anything bigger than like 47" would look hilariously overcompensating for my set up (like you could barely fit a 55" in the space I got, and I just don't need it to looks like one giant screen).
So far, very good, really enjoy the more real estate. Royals games look amazing, as is anything on netflix. Biggest PITA was wall mounting it (which looks sweet just hard to do with just 1 person) and then self made a cable blind since the old set up the TV was basically hiding the cables since it sat on the mantle. Floating exposes them and it pissed me off. Looks much better now though.
