I like it because it's based on Ubuntu, so there's almost always a working guide/solution targeting it. It also ships with Nvidia drivers which saves a lot of headaches for some users. To me the game-changer is the fact that it supports tiling window management with minimal configuration.

It also looks and feels pretty sleek.

Pop!_OS is a solid desktop tailoring of Ubuntu for the hardware.

I would not recommend Pop for server situations, as the desktop trim might be unneeded.
