I am a new Lemmy user (and new to this fediverse, although I have more fediverse experience from other decentralized platforms such as Matrix). I’ve been liking Lemmy, for the pupose it’s thought for, a thread-focused platform (while Mastodon, for example, is post-focused, microblogging). For starters, no advertisements nor sponsorship nor tracking (yet my adblock is active everytime anyways). Possibility of integrating multiple kinds of platforms through ActivityPub (Mastodon, Pleroma, etc). Open and accessible API. Definitely, not only Lemmy is way better than Reddit, but the fediverse is way better than any mainstream social network.
