If it's got helical cut gears that's a possibility.

Neither should show a difference. Brushed motor used alway in forward *might* have the front edges of the commutator bars rounded, which could very slightly affect certain elements forward and reverse enough to call it a difference, but power shouldn't be one of them. Usually just the sound it makes.
Gears also can get "worn in" (out actually)and display a 'preferred direction' noisier in one than the other, and sometimes a bit of power loss too if they were badly mismatched to start with.

the brushes/commutator timing with regards to the poles can be altered so it runs different in one direction
a simplistic brushless controller could do the same with the hall sensors, a smarter brushless controller will probably alter timing in software to get the best performance at any speed/direction

If it is designed to run in both directions, it will run the same both ways.
If it was designed to run in only one direction, it may not run at all in the other.
