Apple II sold: about 6 Mio
Commodore C64 sold: 12-17 Mio
Both used the MOS 6502 CPU.
Commodore owned MOS.
IMHO Commodore and Jack Trammel drove the PC revolution much more than Apple, Jobs and Wozniak.
We are probably still victims of Apple's great marketing.
I'm trying to say this:
Personal computers are about personal as opposed to shared or not-owned-by-you computers and giving computers to as many people as possible. Commodore did IMHO a lot more for this than Apple. In particular in Germany but apparently also world-wide.
I agree Commodore definitely played an important role, but so did Apple, Atari, and also IBM and Microsoft and the PC vendors, the latter group particularly because they most successfully blurred the line between private and professional use
