Smart choice! The option to just try it in a safe way with the live USB is a good way to try it.
Also try out some of the themes in the settings 😉 The amazing wallpapers of Linux Mint are so fancy, so I decided to use it on my work Windows PC, which I am forced to deal with ☺️
I really think you would have a great time with either “Linux Mint” because of its rocksolid philosophy of not breaking stuff or shipping “beta software”.
Otherwise a safe option would be a Linux variant with professional support options - just in case you need it. ZorinOS, Tuxedo or Pop_OS! are the most common ones.
Personally i’d take Linux Mint, which in most cases works flawless out of the box. The premium options are nonetheless also great options.
