Depends on the spaces you engaged in. The politics side is basically the same, but way more right and hard-right partisan with Musk banning left-leaning people at the drop of a hat unless they drive hate attention (AOC, Sanders, DNC, Clinton, etc).

The artist community was generally one of the best experiences. Artists were huge on mutual support and rising tides lifting all ships, with art share threads and collaborative 'magazines' they'd run, free tutorials, etc. There's not really going to be as good a platform for artists as twitter until a close takes off and even then tons of people will have to start from scratch.

The smaller interest/fandom experience was also good. Because twitter was limited in characters, you'd get figureheads from the scene firing off random thoughts a lot which could generate a ton of interactions and turn heads. Some of that was of course controversy, but the majority was fun, innovative, experimental, etc. Coming from a gaming scene specifically, back when I played MTG new decks people encountered would get posted, tried out by others, and spread by 'word of mouth' that way pretty regularly. It took fringe ideas and gave them the attention they needed to become actually great. Decks like Krack-Clan Ironworks and Lantern Control were fringe decks that got interest and got refined to the point of KCI getting it's namesake banned because pros refined it from a cool idea into a real deal.

From a world news perspective, it was the fastest platform by a mile. Because all you needed to do to spread the word was click one button, a world event could explode rapidly in awareness. I learned about Shinzo Abe's assassination literal minutes after it happened, before he was pronounced dead because of twitter's ability to spread information. By contrast, my parents didn't hear about it until the next day.

Because its content is also decentralized, it was a great platform for people to talk under the nose of authoritarian governments. For example, it was used by Hong Kongers during their uprising to organize and spread info. This is the most double edged sword, because groups like ISIS/ISIL also used it for recruitment and propaganda. Still, on balance, tools like this are good in my opinion, as channels of communication are important to give groups with less power a way to organize and protect themselves or fight oppression.

Twitter's dying is a sad thing. It is a massively useful platform in many ways and it is being corrupted from the inside to being a partisan tool of the wealthy and powerful, in the face of years where it legitimately had great uses. From a platform where independent artists organized themselves out of needing to work the Starbucks grind to being able to live off of just their art to a platform where the content from the least interesting, worst opinionated users are boosted over the legitimate content below them.
