KeepassDX has the better UI, but it has some bug’s. Most annoying currently is, that it is not possible to AutoFill in some apps on Android, where KP2A has no problem to do the same. Additional it doesn’t sync with WebDAV or any other network based backend. For this last problem, I use a combination of Tasker and FoldeSync Pro. With Tasker i dedect if KeePassDX is started and send a Intent to FoldeSync to sync the database via WebDAV. There can be a rare situation when both sides of the sync pair has changed, to overwrite one of the changes, but this should be really rare.

KeePassXC vs KeePass is some other story. I really like KeePassXC, specially since I’m working mostly on Linux. But standard KeePass is a little bit more reliable and robust. Additional it has some small quality of life features, what KeePassXC not has. For example easy editing of placeholders for special Autotype Sequences. this is a lot easier in Keepasss. Also to re-use a custom field name for other entries, as long you have entered the field name before. Since I make heavy use of custom fields, this is life saver to have consistent data .
