Considering Howard only really produced for less than half a season, he was hitting .234 with a sub .500 slugging on Sept 1 and was hitting around .200 at the beginning of July, I would give Manny the MVP over him. Plus he wasn't very good in late game/close game situations and really only hit well against shitty pitchers. Struck out 199 times, the most common result of a Howard at bat was a K.
Here is OPS vs pitcher faced ERA.
3.50 ERA or less:
3.51 to 4.25 ERA:
4.26 to 5.25 ERA:
Over 5.25 ERA:

vs Power pitchers
vs Finesse pitchers
vs RELIEF pitching
thats a pretty stark contrast
So you have one guy who hits more HR but that is pretty much all he does other than K, where another guy dominates across the board. One guy just tears up shitty pitchers, the other guy hits well against all pitchers.
Howard isn't even the MVP of his team. If he wins the award the award is a joke. IMNSHO.
