It's all in your perspective. My powershift is not a 5 speed that I have to row through. If I had my way, I would have Cayman with paddles (not gearbox). Shifting with a shifter is pretty fun and yes, affords a level of control; I didn't drive my car as an auto until 6 years ago after 36 years of rowing a gearbox. But do I need a gearbox to do go quickly? I tell you what, not many can outdo me in a corner with a car 10 times as expensive with a manual. I simply brake later, carry more mid-corner spend and with it more momentum to exit with. All the while watching the other car get smaller behind me. There is nothing as sweet as seeing a 30-something in a car they have no clue how to drive, running up behind me, all in tizzy, and then I simply drive away from them when it gets twisty. These cars are incredibly nimble. After I get my suspension upgraded, I plan to AX my SE. I can't wait to see some of the faces when they get smoked by an "automatic"! So is a gearbox better than a powershift? Depends on the pilot. Plus, and this is the bottom line....whatever works for you is just what you need. No one else gets to tell you that you are right or wrong.
End of soapbox....stepping down.
