Pros - My hardware is mine. If I don't like something that shipped with Debian or Mint, I can just remove it. If I'm on Mint but miss something from Debian, there's usually a one line command that will add it back.

Also, most versions of Desktop Linux are free. I don't mind paying for software, but keeping track of Windows license keys was a pain in the ass.

Cons - I mean, it's still a computer. Computers are dumb. Installing it - while way simpler than a Windows upgrade, still took me a few minutes of clicking "next".

I intend for my next computer to ship with Linux Mint pre-installed, because I'm that lazy.

What do I miss from Windows?

Nothing.

I used to dual boot Windows for gaming, but now there's only 5 games in my Steam Library that don't run on Linux.

Five.

I gave up five games, to kick Windows out of my life.

I would tell you which ones, but I haven't actually run across which ones. I only know it's five because I can subtract the numbers before anand after I click the "only show me Linux compatible games" filter button.
