That's very subjective. I have yet to find a Linux desktop I like as much as MacOS, especially when it comes to WACOM drivers. The stylus response time/curve almost always feels wrong.
Also, I've worked with designers who can get something that looks and feels fully professional on a first pass, so it's not just newness for Lemmy.
IMO FOSS has really great offerings when it comes to libraries or other highly technical code.
But something about either the community or incentive structure results in sub-par UI/UX. Obviously not a rule, but definitely a trend I've noticed.
Man I really wanted to like Jerboa but it just has such terrible UX. I ended up signing up for Kbin.social as I thought it had the best UI and now I'm back to Lemmy through Sync.
Yeah, I've been really disappointed in Lemmy's response to sync. I thought this community was supposed to be technically minded but in every thread on Sync, the top comment is repeating disinformation about tracking and there's tons of people tearing down the developer.
I get not wanting to use an App that has ads, but people are getting downright toxic over an App that no one is forcing them to use lol.
