I've tried both Threads and Bluesky and I like Bluesky much better, I mean both UI & UX. One issue I have with Threads is that I stumble upon many users that came from Instagram automatically that are not used to post in this format. So the content is mostly a mirror of IG which makes it pointless. In Bluesky I feel like the posts come from people that fleed X and it's just more interesting somehow.
