I have tried both and liked both a lot.
All other things being equal, compared to each other all-mahogany has a rowdier, more mid-focused tone while the Mahogany+Maple produces a more even response that can also be sweeter and more polite.
That's NOT to say that Mahogany+Maple can't be aggressive and/or rowdy, quite the opposite. Because of the more even response it is actually easier to tweak the tone to a specific direction with pickups.
In the end, it depends what you want the guitar for.
