Have done both every year for the last 3 years. Had to do the backwall the first time to say I had done it. Over the 3 years, the wall was ok, current is strong so its basically a drift dive. Saw some stuff, nothing special, and always faced away from the crater wall to do my safety stop. Pretty cool being totally enveloped in blue.
In the crater, the diving was much more leisurely. Saw lots of Octopi, eels (even the famous Garbanzo), Mantas (two out of three years), and small gray reef sharks. That is of course in addition to the normal reef fish that you can see on shore dives off of Maui (normally).
In Aug 2000, shore diving was assume. Viz was great. Aug 2001 and Aug 2002, viz was bad by Hawaiian standards (20-30'), but totally acceptable for SoCal! So we opted to do some shore and more boat. You need to check with the LDS and find out where viz is best (North or South).
Bottomline, if I only had one dive to do on Maui, it would be inside Molikini -- 99.9% chance of great viz, lotsa life, and a load of fun. If you want to 'dive the only wall in the United States', then do the backside.
