Sync for Lemmy is the reason I’m using Lemmy over mbin right now. The *bin experience isn’t bad per se, but native apps just feel a lot nicer to use on mobile.
I don’t use any apps on desktop, mostly because there aren’t any that look and feel as smooth and complete as the Android apps do.
Also, I feel a bit hesitant as quite a lot of the smap I see seems to come in from *bin servers. Could be moderator actions not federating well? I just need to know for sure that there aren’t any spam scripts I need to start evading after a switch.
I did try out kbin very quick a year ago but the difference in CPU usage for basic federation and browsing was quite large. With Lemmy now consistently using 15% of a CPU core on federation, I dread to think what *bin would do to my poor CPU.
Lastly, I’ve heard some pretty bad experiences about *bin and database issues from people who run both services. Dunno if that’s been cleared out yet, but if I ever switch over, I’m going to need to make sure that’s been fixed.
