Same here, long time Arch then Manjaro user. The only time I run into trouble with Arch was during the switch from the single config file to systemd. Besides that, works perfect. Now Manjaro only with KDE since 2018 I believe. Highly recommended, with yay for Aur. Maybe the advantage of Debian could be the choice sometimes to get old packages version. Recently for example I ran into trouble with Python 11 updated from version 10, but if you are OK with the latest and greatest I recommend Manjaro. PureOS looks interesting also.
