WOO HOO!!! I just got 'em this afternon, so I haven't really gotten a good feel for either of them yet. Here are some first impressions: MXR M-80: Sweet, sweet tone. Really good sounding. I really like the preamp controls, especially the mid. The distortion seems to kinda suck some of the low end out, though, but like I said, I don't really have much experience with it. Well built and really easy to use. Ibanez SB-7: kinda weird, but I'm liking it. it took me a while to get a good sound out of it. The sensitivity knob is REALLY fickle. It's kinda hard to figure it out. I'll put out a better review later, once I get a little more tweak time in on them.
