There’s quite a few right off the top of my head:
Debian
Ubuntu
Arch
Manjaro
openSUSE
CentOS 7
Oracle
TwisterOS
MX Linux
RISC OS
EDIT: Added TwisterOS that I forgot and the last 2 that I just heard about.
Check out Berryboot for a bunch of variants, too.
Actually you should boycott Mint for using Ubuntu repos.
u rite
that amazon thing was unforgivable
Add to that Void Linux and Alpine. 
Edit: just to note, Alpine by default runs from RAM, which is insanely quick on any Pi, but with little hackery, you can make a classic installation on the SD card.
