I had similar thoughts when I first discovered Pop!_OS. Just the name alone gave me vibes of some Fisher-Price toy operating system like it was meant for children, all cringe happy-smiley.

But I honestly suggest you get over your aversion to the name, and give it a try. It’s actually one of the most pleasant desktop experiences I’ve had with Linux, and it’s especially a treat on bare metal. Looks great, runs great and everything just works, including steam gaming.
