Just an anecdote - I never used Twitter/X, and never used BlueSky. Recently (about a year ago), joined Mastodon. I enjoy it, find a lot of value there, and have interesting conversations (recently about Mint Debian Linux & sound-systems, and also maker-space CNC design tools). There seems to be active investment in good features & quality on the platform, including making it easier to host your own organization server.

I believe, due to the format of engagement, its easy to spend a lot of time there scrolling - so consider

(1) only using the platform on your desktop computer, instead of phone,

(2) limiting time - 25 minutes a day is enough!

(3) Mute spammers, complainers, people with negative attiudes - you can't catch them all, but you can intentionally shape your experience over time.

(4) Subscribe to tags of your passions (example: #piano, #makerspace, #drawing, #cats, #jujitsu, #cncrouter, #3dprinting), and try to lean into that instead of getting caught up in endless political reactions - which never ends. You can be intentional, and subscribe to people who have a positive vision for the version of the future you prefer.
