Seems everyone ignores the fact that he wants 4 doors haha. I'd say that if you want a manual, the decision is made...Mazda 6. If you want an auto, just go test drive both and see which one you like better (I'm assuming you haven't already).

The WRX looks more "sporty" than an Accord sedan imo haha. I don't mind the looks of the new Accord sedan except for the rear, the tail lights and trunk seem messed up to me.

The Accord >>> Altima.
