I would have to say Type-R, here is why (btw I own the R and test drove the S)
The R is more race oriented.
I haven't raced any modded type-S but in stock form they never pass me.
The aftermarket for the R is incredible, you will have to wait a couple of years for it to get as big for the DC5.
Some hate the loudness of the R but I love it...
It will be cheaper
All in all it depends on what you like ...raw performance or luxury, security of having a brand new car, modding the car or keeping it stock....
