The exact difference - sorry, that's not me, though I'm sure somebody 
here will answer it. But I can share some experience:

Afaik this has to do with how incoming audio is analyzed, and thus 
how it is processed - peak is the more or less straightforward way; 
whenever the level hits the treshold, the compressor goes to work. 
RMS is more like some average measurement of the source audio level - 
this is where my knowledge becomes quite fishy.
My best results come from compressing drums and other hard attack 
sounds without notable sustain with the peak settings, while using 
RMS for vocals, bass, anything with a sustained sound (actually 
anuthing but "hit" sounds).

Looking forward to the scientific explanation that will no doubt come 
up here on this subject.
