When I was in the Army, we had a real Hummer (as in H1) that got smacked head on by some drunk lady on an Indian reservation. (Long long story as to why it was on the reservation but it was legitimate and there was an officer involved not just a couple of E-4's out farting around.) Anyway, the Hummer got messed up a good deal, but the suburban the drunk lady was in got mangled big time.
H1 most definitely > Suburban.
Besides, what do you expect from an H2? It's just a Yukon/Tahoe Chassis with rather spendy bodywork. Definitely not built to the same standards as an H1. (not even close)
