Lol - I retract my statement now that the ‘big guns’ have jumped in 
I have actually worked with Hyperion, and my original statement was to just highlight perceptional / operational differences re the original statement. 
Yes - it’s getting harder to differentiate between the products what with all the frantic acquisitions that are happening in this realm, but market perception is what it is … and then there are the cost differences to also consider 
But - for a more holistic review of these ‘reporting products’ see my post at Gartners Magic Quadrant 1Q07
