Is the increased performance really substantial? I can live with .1 or .2 seconds more to 60 with a manual. But, iif the overall experience is enhanced w/ the dual clutch, that is intriguing.
W/ older automatics, I always found them non-intuitive and I braked far more than I would like. I imagine the newer dual clutch ones are a vast improvement, by and large. I just haven't tried many.
I can pull on cars with better power to weight ratios just because my progression through the gears to 100 mph is, in total, about .5 to .75 seconds faster than anybody can achieve with a manual and easily that much quicker than a torque converter automatic. They really are that good.
I find that to the extent the transmission fails to anticipate my needs (as any automatic is wont to do, but this one less so), it tends to be conservative with downshifting. The easy fix, with this box anyway, is to drop it into Sport mode. That remaps both the TCU and the ECU and the whole setup becomes a lot more aggressive.
If you want, you can always do the flappy-paddle thing, as well. I don't do it that often because I generally spend a lot more time on regular roads as opposed to roads with a lot of twisty bits. Based on my limited experience, it works pretty well, though.
