Does it allow you to drag a file into a terminal and get a path to that file in the prompt? That's a VERY neat user experience I like about OSX that I miss in my Linux Mint PC.
Those sort of things would make it a "UX alike" instead of only "look and feel"
Hmm, my impression of Pop!_OS is that it's a more opinionated Gnome desktop on a pretty standard Ubuntu base (I like their tiling options). elementary seems like a more ambitious project, but since they don't make and sell hardware too, (unlike System76 and Pop!) it seems like they have more of an uphill battle.
