I’ve tried Mint along with 10 other distros. What I liked about Arch is:
Latest Kernel, always. This means new drivers, better support for your current devices and support for more devices. Security & performance patches.
AUR. Massive repo of user submitted apps & libs most not found elsewhere.
Arch WiKi. Everything you will need or want to do somebody else already did and documented it so everyone else can have a guide to do it. Best documentation site ever.
Arch Repo. Always the latest Software. Officially maintained apps and libs land first on Arch, Debian & Ubuntu derivatives take ages to catch up in comparison.
I use Crystal Linux, which is Arch based.
