I've been in both. The S3 is bloody quick, and comes in 2 flavours of 210 and 225 bhp. I went in a 210bhp one and it was excellent, as said above everything is already sorted on it from stock, the speed, braking, handling is all there. Also the interior instrumentation is nice with a 'enhanced' version of the Golf's trip computer.
The 4motion is more of a cruiser and therefore has more wallowy suspension, still quick off a standing start, 0-60 in the low 7s i think. A lot of people are buying 4motions as a cheap way to get a R32 style car, you get the same 4 wheel drive and only about 30BHP less the an R32, they mod the breaks/suspension etc and chip them.
Its a tough one, but I'd say the S3 and eventually get it remapp'd (I think this can easily take it to 265bhp!)
