I suppose that depends on the use case.  My favorite distro for use as a server (infrastructure/general use/dhcp/dns) is probably Debian.  It’s lean, and reliable.  In some cases I may use Ubuntu Server (LTS) for more advanced web or file services.

For desktop use, it depends again on the use case.  Mint’s great for appliances.  Ubuntu is always a good choice for admin or dev users, but Pop!_OS and Elementary OS are good for general use.
