Depends. Personally I don't consider Popos's DE to be a feature but more of a bug. I think the two competing giants, KDE and Gnome, are more solid and see more dev time and effort put into them, and will do just fine to satisfy all users, preferences and use cases, I don't see the need for the Nth+1 DE that fixes problems Gnome & KDE don't have. But that's just my opinion.
From using PopOS, mostly for other reasons like out of the box drive encryption and nvidia support, the DE's purpose as far as I can tell is mostly to provide a reasonably user-friendly tiling window manager without replacing all of Gnome. Though now they are also replacing all of gnome in the next major release, so who knows.
