Why use it? Probably no reason if you’re happy on debian. It’s just a solid distro and as other have said the best out-of-the-box desktop experience out there IMO. Definitely not going to win over any KDE fans but their tuned GNOME DE is really slick, and it’s only gonna get better when they release their own DE “COSMIC”.

I’ve been dailying Pop on all my main machines for years now without any problems. Think of it as Uncononical’d Ubuntu in a way but they’re really committed to making a unique footprint
