no competition, of course the Nissan wins if u pick the correct color. The gun metal grey looks just great.

for long term reliability, both cars also known for it, so both also good

for 2nd hand value, both also the same shxtty when u wanna sell them, but the Nissan wins a bit in this department, the Mazda just doesn't cut it, u'll loose half it's value when the warranty runs out

for comfort and power, Nissan wins. if u care about comfort, there just isn't any competition.
