On the other hand, PPC asm is a comparitive breeze. The exe's are big, because it is RISC code and needs more instructions, but its a great deal more efficient. It doesn't have 200 extra instructions no-one ever uses, so the decoding time is measured in picoseconds rather that nanoseconds. PPC is a lot better than x86, period.
It may be, but RISC chips like the PPC are not really intended for direct machine language programming, due to the increased amount of instructions (and thus increased program design complexity) it takes to do anything. It's designed to make writing higher-level compilers easier...
