Love:
Z80
68020
68030
68060
PPC 603/604
G4
Socket A Athlon
Core 2 Duo and derrivatives
Hate:
Pentium family from original up to 4 - what a load of crap!
68040 - so hot and incompatible at times
G3 - underpowered for what it was advertised
G5 - inferior to G4 (higher clocks though)
I think I've read somewhere that 68060 and the original Pentium are quite similar in design? Or something like that...
