For me it was great. I've been trying to leave that shithole for years; Lemmy got enough content quantity and diversity to keep me entertained.
I do miss a few niche subs; mostly r/conlangs, game-specific subs, and a few subs for anime/manga/LN series. But I don't really feel missing out.
I also miss behaving like a shit-flinging monkey and chimping out. I don't do this here in Lemmy, but I did it all the time in Reddit. I guess that I contributed to what you call "hateful people"? Perhaps not, you don't look like the sort of user that I'd chew on.
The issue I have with Reddit - it’s full of hateful people and most content is just bots karma farming.
My issue with Reddit is also the userbase. But it's on another level: the local culture of Reddit encourages braindeadness, disingenuousness, entitlement, and circlejerking.
