Why use Pop!_OS? I guess because the name makes you look like a 1337 h4xx0r.

Joking aside, Pop is generally liked for its easy-to-use interface. System76 has made a well-polished suite of software, and they are in the process of replacing GNOME with their own DE to make it an even smoother experience.

Of course, if you use something else (I prefer openSUSE Tumbleweed), you can just stick to Flatpaks entirely without having to get concerned about snaps.

I use Pop OS (mostly) but there is not a super compelling use case for if you don't want to just go with their defaults. Pop OS is a time saver in the sense that it gives you a bunch of things out of the box (disk encryption, tiling window manager, NVIDIA drivers, Apple-like recovery partition in case anything goes wrong, etc) that you could set up yourself, but don't have to.

You can basically set up Ubuttnu or most other common Linuxes to be just like Pop OS by spending a few hours on it.

For people using another distro without customizing it much after the installer is done, then I would usually recommend Pop OS. I think it's the best "out of the box" Linux for most general-purpose computing like programming, email/web, Slack, etc.

But if you already switched to Debian and are happy, then there's probably no huge benefit to moving to Pop unless you are sick of tinkering and just want automatic system updates that keep you pretty up to date with recent kernels and packages without you having to do anything.

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
