Funny thing is most of the comments are probably from those who haven't driven both. Just about any other AWD can't be launched by reving and dumping the clutch, except the STI. When you get a launch right with some crafty clutch slippage you will feel like someone launched you from a rocket.
I have a 3" catback on my WRX and that might make a small difference when the turbo spools but it starts around 2500-2600, and by 3000 it is on all the way. That sucker pulls HARD, and I have already dispached a few takers who doubted.
The car is deceptive though to, at 120km/hr it feels like 70km/hr, where as I thought the MSP felt like 130km/hr at 80.
I know the MSP has more impressive handling figures but the WRX still can hold it's own in the twisties for sure.
As far as the interior goes, the MSP gets the edge with the sound system but the WRX takes it back with the seats, otherwise they are =
