Both types of transmissions are capable of shifting much faster than human reaction time and in fact both are faster than "The Blink of an Eye" whch is about 300-400MS.
I have driven the DCT in both the 335is and the M3 and found it to be an excellent transmission but did not find it to be significantly better than a good AT. IMO a lot the appeal of the DCT is that it does not carry the stigma of being a "Slushbox"

You make a good point. I haven't driven the IS-F but I've heard that it shifts very fast. The 7-speed auto in my car could be faster though.
