The engine is tuned to have more of a flat power curve to try and hide any turbo lag. This is probably why people say the V8 feels more responsive than the V6 despite only a 20hp difference. The curve matters a lot, its not just about peak power.
The suspension is also tuned differently, to be more sporty.

And ultimately if you don't mind tuning your car (either dont care about warranty or dont have one) then the GTS can be tuned to Turbo S levels (same engine after all)
