I'm tempted to say it's better, but, unfortunately, in many ways it's not.
What Reddit had, most of the time, was semi-canonical communities. There was /r/python, /r/linux, /r/privacy, etc. The diaspora of Lemmy is a shadow of all of that. Surely, there are a dozen or so (at least) /c/python communities on Lemmy, but is there a single one that's anywhere near as active as the Reddit one? No. Not so far, at least.
And unfortunately, I can say as an instance admin, the lemmy moderation tools are just flat bad. We had to turn off open registration and enable email verification, not because we would otherwise need it, but the Lemmy moderation tools are 100% reactive and only operate on a 1-by-1 basis. If a spambot signs up 100 fake accounts, I have to go and individually ban each and every one of them. There's no shift+select, ban.
Don't get me wrong. I'm glad to be here, and Lemmy's great, and there's far less toxicity (so far). All I'm saying is, (1) there's work to do, (2) don't gloat.
