I have an account to follow artists on X. Surprisingly, it never pushes even one single blatant AI artist to my feed (not saying I'm an expert to recognize AI-generate artworks, but I've done digital painting as a side gig and.) There might be some paintover or more subtle ones that eluded my radar, but I've never seen the typical AI styles on my timeline.

However, if you check posts remotely related to the US politics the reply section is out of control.

I honestly believe out of Reddit, Facebook, Bsky and X, X is the one with the most reasonable timeline algorithm[0]. Reddit and Facebook are unusable except for very specific reasons (asking questions in certain apps' subs/groups). Most people I know irl moved to instagram though.

[0]: Bsky is the worst, but interestingly if you use a third-party feed like 'For You' it's on par with X, just less traffic.
