As someone who doesn’t generally play with children’s toys, i still say the answer is never.
As Randall Munroe said way back in XKCD #150, we’re the grownups now, and we get to decide what that means. Life is too short not to spend as much of it as you can doing what you want. So long as it doesn’t interfere with others, go wild.








If you’re new to Linux: Mint. Use Mint, with Cinnamon. Or MATE, if you’re hardware is older. It works just how you’d expect.
There’s many other distros for other purposes. Bazzite has a lot of people who like it for games. If you really want to control EVERYTHING about your machine there’s Arch. If you want bleeding edge software and don’t mind/can fix the occasional problem caused by rolling releases then I suggest Manjaro.
But most Windows refugees will be looking for something familiar that works and stays out of their face, and for that the simple answer is Mint.
