Not the OP, but I made a similar transition. I got fed up with using APT to manage packages while Yum/DNF seem much more complete and elegant. I seem to get far fewer package conflicts with Yum, and the error messages when something does go wrong are more digestible, though this may be just due to my use case/package selection. I also dislike the use of the dash shell by default. To me, it just further muddies the water between compatibility of sh, bash, and dash. I'd rather just have bash and be done with it.
Fedora's packages are also more up to date while being as or more stable than Ubuntu. Debian is still probably king of stability, but when compared to CentOS, I prefer CentOS' default package selection and configuration (postfix vs exim, sudo installed by default, ssh installed and enabled by default) , especially since they embrace systemd while Debian seems to use it grudgingly while also keeping around old methods of configuration that don't quite fit with systemd (network configuration being the big one here, don't even get me started on Ubuntu's adoption of friggin' Netplan)
Thanks for the reply. The past 9 months I've had to dive deep into rhel again, and it's been a disappointing experience, but that may be due to a) more than two decades comfort with Debian, and b) some number of third party addins to rhel 7 systems, but conflicts have been much more painful in the rhel side. I've never noticed or been bitten by the dash / bash arrangement. package selecting in both cases is defined by cfm (salt or ansible) so I've never felt pain in that front either. Systemd seems to be full commitment by Debian, including network config, but perhaps the migration scripts weren't working for your system(s).
