Is the question about Linux in general or about Pop_OS specifically? I've used it--the differences are going to increase once their new desktop environment releases, but right now it's comparable to Ubuntu except with some nice-to-haves (proprietary NVIDIA drivers are installed automatically, no software is delivered via Canonical's 'snaps' which are almost universally hated). I enjoyed it, but in my opinion, popular distros are more similar than they are different.

If you mean just replacing Windows with Linux in general: it's great, unless you need to run, say, Adobe Photoshop, Microsoft Excel, or Fortnite.
