more than likely handle better due to the Quattro but, which is faster!?
S3 isnt quattro, Handling wise id say an Ed30 would be better than the S3, unless wet.
If your mates stage 2+ got embarassed by a standard S3 either
a)there is an issue with the ed30,
b)there was a big style loss of traction on the ed30(easily possible in this weather) or
c) your mate cant drive
My stage 2+ vRS was notably quicker than a standard S3, so a stage 2+ ed30 should and would normally annihilate it
