I definitely prefer PowerMac.
However I wish they would go back to the name and number system.
If someone said they had a PowerMac 9600/200MP. You knew it had a dual 604e running at 200mhz, case design and expansion capabilities. Whereas if someone says they have a Mac Pro you have no idea: what CPU is in it, what generation it is, what expansion capabilities does it have. The iMac being the worst offender being you have no clue: what it looks like, what CPU architecture it has, what its expansion capabilities are, or basically any useful information. All you know is that it is a G3 or better and a desktop computer.
This held true for PowerMac G3's, G4's and G5's as well. So they had to be given sub names to at least define the Motherboard generation. With G4's you must say Yikes, Sawtooth, Gigabit Ethernet, Digital Audio, Quicksilver 2001, Quicksilver 2002, Mirror Drive Door or Firewire 800. With the G5's it is Revision A, Revision B, that one just before last🙄, and dual core.
