Once I found Liftoff, I've used Lemmy exclusively. It's fantastic, I don't feel as intimated about commenting (even though this is my first on this account) I've found most of my interests again in different communities. There are still a few I don't have, but that will sort itself out in time.
I never used relay. I was a RiF fan, I had that for years.. so long that I actually forgot Reddit had ads!
I tired mastodon on the mobile web, but that just didn't gel for me, the few times I've logged on to Lemmy on the PC it's also just felt so much easier to scroll and read.
