From my experience so far, I believe a standard, robust, but lean enterprise-grade Linux distro (like openSUSE non-rolling release) is the best, and then you install just what you need. Most stuff in these 'Bitcoin distros' you don't actually need for running Core.

I would of course recommend my own guide for Bitcoin full node setup:
FULL NODE OpenSUSE 15.3 walkthrough: bitcoind + electrs + c-lightning + RTL

Feel free to omit electrs and c-lightning, if you don't need them.
