I say both... depending on what you are playing.
I say this as someone who has a wide tent in what I like. Everything from Turnbased RPG - Action RPG - 3rd person action game - fighters - fps - stealth - turn based strategy -rts - grand strategy - card games -puzzle games, survival horror, driving, space games, etc.....
Some genres are better on a certian screens.
Now as for screens themselves, I can't really comment on new stuff. I am still sporting a 2020s era 1080p 27" 144hz monitor for my pc and a 2013 1080p tv with all the inputs that modern tvs don't have. To me its hard to throw away something that still works fine. Why get rid of a perfectly good tv? It also has 4 hdmi, vga, composite, component, svideo, usb and rf, how many new tvs have that many connections? Most just have 2-3 hdmi and that's it. I still sometimes play the ps2 and older retro consoles or mini-consoles. Those need the connections and how would they even look on a 4k display? Maybe good, maybe not, I'll try it when the tv breaks.
What am I missing not going to 4k? This isn't like going from sd - to hd where it was night and day clarity.
