For me as a 'drivers car' its simply not as involving and fun as a manual
If I were buying a sporty car I would be torn, to be fair. Manual is good for driving yes but the DSG shifts far better and quicker than you ever could, with no break in power. The feeling of ripping up through the gears with instant changes is great.
I would have to think twice about speccing one on a new car, due to cost, but I do think I would miss it if I didn't have it.
By way of explanation, since we're here, the gearbox has two shafts, one with 1 3 and 5 on, the other with 2 4 and 6. So you're in 1st accelerating and it pre-selects 2nd on the other shaft, and because there are two clutches it can switch over to the next gear almost instantly. Then whilst you're accelerating in 2nd it selects 3rd on the other.
The only time there's a delay is when it decides you want a gear other than the one it's got pre-selected. So if you are accelerating gently or trundling in 4th say, it'll have 5th ready to go but if you then stick your foot down a lot it'll decide 3rd is better, so there'll be a delay of about a second whilst it engages 3rd instead of 5th on the other shaft.
This NEVER happens when you are giving it the beans on the open road - only when you are changing tactics. When overtaking, you have two choices. You can pre-select the gear you know you want in manual mode, keep it there and then go - exactly like you would in a manual. Or, you can just bury the pedal. As above, if you do that it'll select the lowest gear it can which may take a second. However the nice thing is that it'll also pre-select the next gear at the same time so in that second you'll be at peak power, then get an instant upshift. Despite the second's delay I think this is still just as quick overall as manual.
