I'm not interested in having my OS as a hobby. I prefer it as a functional tool that lets me do things with minimal effort required. Not hating on arch, just not my thing
I wouldn't say Arch is a "hobbyist" distro, just one that gives users a bit more control over the install. Maintenance is the same as with other distros once you have it set up imo. Not saying you should switch btw, if you like Mint keep trucking with it.
