Or heck, even if you have just listened to both, impressions please. Which one would you buy? Did you buy one after looking/listening to the other? I've kept remembering how pleased I was when I borrowed an old Peavey tube guitar head and ran my RBI into the power section. Tone that I just never had before. Not exactly on the verge of getting one of these as I have to replace my micro-head amp first. But I may start looking.
