Huh, it’s been nearly flawless for me as well. Had it randomly hang once a few months ago but I think that may have been due to a lack of resources for that lxc. Other than that it’s been flawless over multiple apps: Linux, Android (element, schildichat next, fluffy), windows, web. All synced and verified.

I looked at the comparison for Seafile as that’s the one I’m most familiar with. In my opinion Seafile’s greatest strength is its encryption, but in your comparison you seem to see this as a negative as I assume this bullet refers to the encryption? “isolated on-disk file hierarchy, incompatible with other software. much worse than nextcloud in that regard”
