You like the PowerPC to program in assembler?

I've never tried, but it looked several times harder than 68k.

Not really, its just more instruction names to remember move does many things on 680x0 depending on syntax with '(' and ')' or whit out, PowerPC assembler does not have that.

Most PowerPC instructions have 3 parameters, parameter 1 and 3 is normally source and destination, number 2 is often optional, normally used for indirect addressing.

Etch of the letters in the instruction normally stands for some thing, if you remembering what letters stand for you can guess what the instruction does easily. If you spent just as much time whit PowerPC as 680x0 you remember the names.

'S' Store
'L' Load
'Z' Zero
'R' reverse order (little endien mode).
'X' Indexed addressing.
'B' Branch

And so on.
