We all have things we like, it takes a while to be proficient and I don't think anyone is a master.
Well, I've definitely met some Linux masters in my day....including his holiness Linus Torvalds himself, but as has often been stated here PowerPC Linux is not for the uninitiated, and its headache upon headache compared with x86 Linux. Full props to those who do it (like ppcluddite) of course. You are limited to just a handful of distros, most with community only or spotty as hell support/documentation. MintPPC had a lot of promise but is not under active development at the moment. Stick with OS X on PowerPC unless you are looking for a learning experience, in which case, have fun with that. If you have an old PC lying around here are my recommendations:
Best distro for old (five to ten years old) PC's: LXLE runner up: Lubuntu (lxle is based on lubuntu)
Best distro for really old (ten to fifteen year old) PC's: AntiX, runner up: Puppy
Best distro for newer (last five years) PC's: Linux Mint
Best overall Linux experience: Ubuntu or Mint on a ZaReason, System 76 or Think Penguin machine, as they are specifically designed to work out of the box with Tux. Kinda like how a mac is designed to work out of the box with OS X.
