I used KeePass + Dropbox/Syncthing for years, but eventually gave up. At some point I saved my KeePass db with a newer version (of the software and the DB format), and later found out that the newer software version will not run on an older version of MacOS that I still use on one machine. I mean, I could maybe update the OS on that machine (not sure--it's over 10 years old) but at that point it was less work and less risk to switch to BitWarden. And the user experience is much better as well.
