I used a bit of Linux Mint, Ubuntu, Lucid Puppy and some variations of Debian before on multiple computers, but not enough to fully understand it.
Have used Windows for a very long time and I am kind of a power user (screw powershell, I am not touching that)
I have not tried Pop OS, but from what I have read, it is used mostly for gaming and can be a good beginner distro. From experience, if you are coming from Windows, I tend to recommend Linux Mint Cinnamon.
