I have a 2017 laptop with Windows 10 and I am thinking of installing Windows, but I can’t decide between Mint and openSuse. Anyway, I have until October to decide.
Both are good options! As is Ubuntu. You could make a Ventoy usb drive, and put all distros on it and spend some time in the life environments of each. This will leave your Win10 install intact and give you a feel for what you like. You can even install packages in the life environments.
