At the moment I think BlueSky is a really mixed bag. The functionality seems fine to me but it's undoubtedly jankier than pre-Musk Twitter.
On the other hand, I hadn't realised how much adverts and algorithms on Twitter affected the user experience until I used BlueSky. Even exclusively using the "Following" tab on Twitter it regularly seems to decide which tweets from people I follow I want to see or not and obviously it chucks a bunch of ads at you regardless. Going on BlueSky and actually seeing every post the people I follow have posted in reverse chronological order is refreshing. Seems to be better for content creators too - a few artists I follow have said they're getting way more engagement on BlueSky than they do on Twitter despite having a fraction of the follower count simply because the people who follow them actually get to see their posts.
The big issue with it at the moment is simply that there aren't that many people on it and it feels "quiet", but it's possible that's also the only thing which is saving it from immediately becoming a toxic hellhole.
edit: wow actually it is running slow today, maybe a big influx of twitter emigrants following the no blocking fiasco
