HAHA! I thought he was Japanese.
Haha, your wild guesses does not surprice me. On YouTube I was named Polish, no EAB they said I am Czech, now Hungarian, Japanese.
I does not matter much in which of these countries, because in any of them you will have a hard time getting fully working Mac for MOS except may be in Poland.
On the other hand I order from Vesalia since 1999 and had no problems receiving my orders (Amiga 1200, AmigaOne, cards, magazines, books, software, games). Currently Vesalia have listed Amiga and AROS systems for sale, but not MOS capable hardware.
If the AmigaOne X1000 AmigaOS 4 port is properly done it will be the first AmigaOS to take advantage of dual core architecture that will make it porting to G5 Macs more trivial than the much anticipated G5 port of MOS which is not there yet.
To answer the OP question: AmigaOS 4 on PPC Mac? No, I prefer it on new hardware. It is irrelevant if my MicroAmigaOne (from which I am typing this) is old or new hardware. I bought it first hand.
