No difference in quality as far as I'm aware.
Maintenance is a different story, but the difference really isn't that big. Dye transfer can be a problem on lighter coloured seats, but if you clean your seats on a regular-ish basis using a mild detergent, you shouldn't have any issues. Black obviously hides most stains and stuff much better, so you'd probably be able to get away with not cleaning them as often.
Black leather also absorbs and retains more heat in the sun, so parchment coloured seats will be easier on bare skin, and the interior ambient temps will likely be lower compared to that of a black interior.
