These are applications ( Steam is a nice platform ) not Distributions. Debian , Arch , Fedora in my experience have the best access to the software needed to customize your system to your needs. Arch is my favorite.
If your question is what comes pre set up with most common tools without user input then it is Linux Mint which is based on Ubuntu / Debian.
Howver if you want to customize to youre needs you are better off with a base distro & build from their. Just my opinion.
