Alright Robby, because I love you so much.
Staves add magic affinity, which add 0 mab. Magic affinity is calculated at a different point in the equation for determining magic damage and it adds a whole lot more damage than MAB. I'm not going to explain exactly why this is, but please please trust everyone when they say the difference isn't even close.
Staves are just a direct 10/15% Bonus(NQ/HQ respectively) to the damage near the end of the calculation of magic damage, versus MAB+10, which is not a 10% bonus to your spells, (Unless it's being factored in QD damage, in which case, 10 MAB would be 10% to your base damagex2 blah blah, BLM section etc)
