Which is cooler/more fun to drive/gets more chicks/will increase my size 1-3 inches in 6 weeks?

I had my heart set on a 2000 S4 with a good balance of handling and power mods, making 450hp with a nice, flat torque curve, 18K.

But last night, I noticed a 2003 IS300 in Destin with a 2JZ-GTE swap, huge turbo, water/meth injection, etc. making 570rwhp on pump gas, for 15k.

So which is better? To enjoy the flat, straight roads all over Florida, leaving rubber at every stoplight but treading carefully in corners and in the rain? Or to hook up awd and a well-tuned chassis to the pavement and enjoy the curves when I can find them, whilst possibly paying more for maintenance?
