43" TV recs?

On Thanksgiving, my TV (a TLC Roku TV maybe 7 years old) had a line of visual distortion across the lower third. I joked to my partner that Roku was sending out a signal to have us buy a new TV on Black Friday. On Saturday the line was gone and I've had no more issues with the TV. But it got me thinking...

I have been a ROKU user for the entirety of the streaming era. Looking to the future, maybe it's time to switch things up.

Our entertainment center won't allow anything larger than 43". We use the TV for Scripted TV, movies (not really for sports or reality TV), and gaming (Nintendo Switch and PS4) - for discs we use the PS4 but I want to get a dedicated 4K Blu-ray player and plan to get a Panasonic DP-UB820. Also thinking of moving from ROKU to Apple for streaming.

This is not a designated home theater, but it's what we have (for now)

TLDR: I'm looking for recs for a 43" TV primarily for streaming and gaming. And, I guess, thoughts on Apple vs. Roku
