If Windows works fine for you and there's no issues, probably no reason to switch, honestly. If you want to try it, I'd say maybe start with virtual machines and then see if you want to dual boot.
It's easiest to transition to Distros with more Windows like UI's, particularly if you like to put app and game icons on your desktop. Believe it or not, a lot of popular Desktop environments (especially Gnome) don't allow you to without some major finagling.
I personally recommend Linux Mint with Cinnamon, Kubuntu, or ZorinOS to get started. Trust me, while playing around with different distros is fun at first, the novelty wears off and eventually you just want to log in and have it "just work". I spent a year on Mint w/ Cinnamon because it just worked for me.
Note that even if you switch, it's still probably best to dual boot as some things just won't work on Linux or is too time and energy intensive to be worth using on Linux. The opportunity cost involved makes doing some stuff on Linux just not worth it for most people.
