Foglight Vs AWR/OEM etc

I would appreciate the opinions of anyone who has used OEM/AWR/Other Oracle tools and has also used Quest's Foglight for Oracle product. Did you find one superior? If one was only incrementally better, were those small differences frequently invaluable?  

I'm sure more of you have used the Oracle tools than the quest tool so here is the Quest glossy-ware.
