They've actually done a very good job in purging the bots. When Elon first took over there were crypto and "adult activities" bots that would tag me and as many other users as they could about five times a day. I haven't seen one now for the better part of the year.
The experience on X is a lot more enjoyable than Facebook is, at least for me. I've noticed that Facebook has far less content from my 'friends' than it used to, so I see stuff from random pages and groups that I have little to no interest in. I gather that this is due to both a decline in engagement from the average user, as well as algorithmic changes. Just this morning I saw four posts in a row with the same picture of Imelda Staunton receiving her honors from Prince William. It was nice and all, but once was enough. X, on the other hand, shows me stuff I'm actually interested in and from the people I choose to follow, and in the 'For You' section, it does a great job of mixing in people I follow alongside that which I actually enjoy seeing.
