All major Linux distributions are roughly equally trivial to install these days. Mint is actually harder due to the relatively old kernel at least having more potential for lacking hardware support causing issues. The actual process is get similar for most of them.

Frankly the installation isn’t what is likely to cause issues for most people. But something breaking down the line, or wanting a new something (at adding app/functionality/running Windows program/…). How hard/easy it is for them to figure out how to fix that.
