love 040/060... even 25Mhz versions made using Amigas a true pleasure. I still remember my Falcon040/25 A1200 accelerator :-)
hate: 030... it was an accelerator but miggies don't look fast with it, even decompressing JPEGs takes ages
love G4: altivec was an elegant idea.
hate any 603 derivatives: crap ppc performance, makes me remember the old A1200/030 dark times when users who only played games were ignorant about 040 superiority
love 68000: it was incredible how many things you could do with a 7Mhz cpu!
hate 68010: an useless upgrade (more or less like 030 boards only used to launch whdload games due to availability of extra ram)
