I have used Linux for a while and transitioned the wife and kids to Linux Mint a couple years ago.
They know it is different than Windows but never miss anything as the alternatives are as good or better. The kids are used to mobile and tablets so know of app store and so on. The only downside is getting some games their friends play working, like Roblox. But for the most part alternatives like Minetest are fine (better).
The upside is IMHO massive in terms of privacy, security, user friendless and sysadm stuff.
It just works and we're happy with it!
