I've driven both S2000 and BoxsterS

I Autocross a fair bit previously with a Miata with LOTS of upgrades.

The S2000 is an A+ car for track or autocross. Best value in roadsters by a mile.
The BoxsterS is also A+

The S2000 has a much better gear box and is bullet proof.
THe BoxsterS has better brakes, better handling, better steering, better
seating position, and of course low end torque is way better than on the S2000.

I also like the STI, which says allot coming from a guy who thinks all cars should be sold with two doors by law.

Also, for Autocross I think there is a big difference between the BOxster and Boxster S. If you plan do allot of Autocrossing with the Boxster I would not go with anything other than the S. At this curb weight the car needs at least 250 HP well it doesn't but with 250 coming out of turns and tossing it around is a vey difference experience in the S. I regularly match the 993 and 996 911's without really pushing. Meanwhile some very experienced and very good drivers in Standard 2.7 Boxsters are a good 1 to 2 seconds behind the Standard 996 911's.
