Absolutely. Any Ubuntu or Ubuntu-adjacent distro will be very user friendly. Mint Linux is a good one, but plain old Ubuntu is fine. There may be some edge cases where to get something done or tweak something you might end up having to copy and paste a command into a terminal, but for the most part it’s all graphical. Also, installing Linux is faster and easier these days than installing Windows. If you’re a gamer, but your gaming is done through Steam you might not even notice a difference between Windows and Linux for gaming at this point.

edit: my mother’s in her 70s and has been using Linux for years now, I installed Mint for her a long time ago and she’s been happy with it ever since. I have to help her with Linux stuff less often than I have to help her with her Android phone, and she’s an extremely non-techy person.

It’s better than its been, but it still lags behind Windows. It’s like 80% plug and play, 15% can-work-if-you-fiddle-with-it, and 5% doesn’t work. That’s the real reason it hasn’t taken off, IMO - people won’t switch devices unless you give them a compelling reason, and all of the compelling reasons to switch to Linux are things the average user really doesn’t care about.
