Stock Debian has been pretty decent recently. I was surprised to find it either didn't require proprietary blobs or installed them when I wasn't paying attention.

I've also been playing around with BSD and it's like hanging out with a friend from elementary school: they're a little wonky, but you remember some good times together.

PopOS isn't my favorite, but it is pretty straight-forward. If it's working for you then it's a total win. (Which is my way of saying "though I like Stock Debian and BSD, there is absolutely nothing wrong with PopOS.")
