I tried it first and swapped away. I know I didn’t like how Radicale required editing text files to add accounts, that’s for sure, but the main reason I swapped was that the Docker environment kept freezing and using up 200% CPU until I manually restarted it. Rinse repeat every few hours. This was on a new install with 1 user. No issues since I moved to Baikal and the web UI is much nicer.
