I don't remember exactly what the problem areas were but it had something to do with kits and breakouts and how they are handled differently. It would have caused too much disruption for our operation to change.
Desibold,
Thanks for the input. All of our items have their own part numbers - and we group things using parent / child relationships on the cart level. I haven't really looked at these types of features (kitting, composite, breakout, etc). If this is the only advantage of MOM over Stone Edge that this forum can come up with - I'll probably be switching fairly soon.
