OMD the most because we lost continuity. Trying to read them differently in some instances don't even make sense anymore.
OMD is like the Clone Saga in such that much of what you knew was wiped out. The only difference is OMD has stuck.
Although both stories were horrible for what they did to spiderman I can't say I didnt laugh when Sins Past described how Osborn won over Gwens panties with his "Animal Magnetism". I laughed for 10 whole minutes on that line.
