Another factor---don't know if this applies to anyone else, or just me.
I'm a weak backhand player but a terrible forehand player. I resort to it so rarely that the clowns I play tournaments with reach for their cameras when I take a forehand stance.
But I played at Ashe County where I had some long, steep uphill upshots, with a stance on a steep slope that allowed no footwork. (Probably better players don't end up in these situations, but I sure did). Once I was out of contention, I discovered that I can stand-and-deliver a 45 degree uphill shot much further forehand than backhand.

Another advantage to throwing both is sometimes you can work around an injury that hurts throwing backhand, but not forehand. Particularly knee injuries. (This advice primarily for Masters & above).
