I still use a 1080p monitor myself, so I'm almost certainly benefiting from AA more than your 1440p or someone else with 4k, so I can see why you would prefer it off since it's not quite as needed anyway. I imagine at 4k on a smaller-ish screen AA may not be needed at all.

But generally I like to play games when I want to play games

As I've begin to try out older consoles for the first time that only output 480p (like the Wii), the aliasing on a modern TV can sometimes be distracting enough to detract from the experience, something an old CRT with its natural anti-aliasing probably would've been less noticeable.

I agree that raw resolution is king, but for those of us with lower resolution hardware, I don't feel like anti-aliasing makes a game less of a game, personally.
