Definately, without a doubt, THE S4 (WHY, are you second guessing yourself
?. For one thing a stock S4 will smoke a stock WRX. The commercial on TV is WRONG! Car and driver had a slightly modded WRX for their commercial. And anyways, Subaru has changed their mind about 10 times about how fast that car really is, but stock for stock (search around) it is documented that a WRX can't touch the S4. Also around 2500 in mods (500 Chip, 1700 downpipes and exhaust, and 200 intake) the S4 easily makes around 320-350 HP and about 380-400 Torque! Will easily run low 12's on a good day...hehe. GET THE S4, you will not be disappointed. Also, IMO, the WRX's are dead ugly compared to the S4...the level of refinement in the S4 is much sweeter than the WRX cheesy interior & exterior.
