Redditfugee here. Lemmy pros/cons:

Pros

• I guess it serves as a bit of a nicotine patch for Reddit. I'm no longer active on Reddit, and I spend less time doom scrolling than I used to.
• By and large the community seems alright.

Cons

• Lemmy just isn't the reference omnibus that Reddit is, and I don't think it ever will be. Even down to r/whatisthisthing or r/tipofmytongue I don't think will work on Lemmy, partially because there's going to be eight of each, seven and a half have no traffic.
• The communities I'm interested in have basically no traffic. No one posts anything. I see a lot of posts with no discussion, or one comment saying "I'm a bot."
• There's a kind of stupid problem where, you're scrolling through, say, your All New feed. It's separated into pages instead of infinitely scrolling. Page 2, you find a post you'd like to read. Click it, read the post, back out to the feed, you're on Page 1 of the feed again. You've lost your place. One of the ingredients to that nicotine patch.
• There are too many different forms of idea cancer here. I spent several minutes having to individually block several nearly identical communities for sports ball game results that each had nearly identical bots posting sports ball scores to them, because someone set up a nearly identical community for each team. This I think is a valid use case for the platform, but if you're not interested in sports ball it makes the All feed unusable. I'd also like someone to explain to me why posts from r/buildapc are being "archived" here?
