just lemmy or the federation? im on mbin and I left with the big reddit migration and was pleasantly surprised to find something a bit closer to the old internet I knew. Im one of the few who don't see the need for it to get popular but its fine to me if it does.
I tried both when I was deciding and liked kbin at the time (I don't know what happened to earnest and really wish I did). this was due to the web interface though and I only use a laptop so I don't think the interface matters with smartphone users as much as they I believe have a variety of apps that can change it around.
