Mint is up to date but less buggy than Ubuntu, and it has served me well for years without problems. The UI is very conventional so I don’t spend time thinking about where stuff is. It supports multiple packaging systems now, so it’s easy to find and install software. You don’t have to go to anywhere as dodgy as the Arch User Repository to find what you need. I like Mint because it’s boring and it works and I can just get on with stuff.
