The answer to your question is that it depends on too many things to be able to make generalizations.
Do the cars have the same tires, or does the RWD car have narrower tires at the front and wider at the rear than the AWD car?
Is there enough engine power to spin the tires on both cars?
The AWD car will have a lot less problems with wheel slip, but that could be somewhat balanced out by having different tire widths on the other car. It also has a less efficient drive train with more power loss. Because of this it will launch better, but depending on the engine power it may start losing ground (because of drivetrain power loss) once the RWD car gets good enough traction to apply full power to the ground without wheel spin.
Also, torque-based weight transfer under power will be different for each car because of the difference in front/rear power distribution.. This will affect a few different things even if both cars have the same spring rate and everything else.

I appreciate the speedy replies. You guys can carry on with your lives. Thanks.
Same tires on both cars, the AWD drive will always win off of the line if there is enough engine power to spin the tires on the RWD car. If you can't put all of the available power to the ground on the RWD car, the AWD car will always have the advantage, because it can use a lot more of the available power.
