Debian all the way.
Used to use Ubuntu, but then they lost their way and went all sucky (both Canocial and the software itself).
Used to use CentOS, but then they lost their way, e.g. CentOS 8 was in the pipeline for an eternity, meaning CentOS 7 packages became increasingly rapidly obsolete.
Tried Alpine Linux, I really wanted to like it. But it sucks. The team managing the AL product is a bit stretched. Plus some of the design decisions make it a bit of a pain (e.g. DASH, musl libc etc.)
Tried OpenSUSE but found it a bit too opinionated for my liking.
So I settled on Debian, and the same on the vast majority of server instances at work.
Debian is solid and well maintained, and I prefer their erring on the side of stability rather than bleeding-edge (most of the packages are still reasonably in-date).
