For you friend, it's fast. Two questions though need to be addressed perhaps separately. What would a 1M do with its existing ratios (gears and FD) just with faster shifting? Secondly would 7 gears and altered ratios help? I'll answer the first part quickly as the second part takes much more time.

In short a 6 DCT would provide about:

0-60: 0.2s improvement (just about the wasted time of a really fast shift in the MT)
0-100: 0.4s
1/4 mi: 0.2s, 1 mph trap
0-150: 0.9s
60-130: 0.4s

Not huge gains for no ratio changes.

Car #1 is 6 MT, car #2 is DCT.
