What does skipping gears get you that quick sequential shifts don't?
My feeling is the opposite. Paddle shifters are the closest I'll get to driving an F1 car, and I've put a decent amount of time in with a racing wheel and pedals and racing sims and that's where I get all of my muscle memory for my Golf GTI.
I can still skip from 2-6 on a freeway onramp or 6-4 for passing faster than 8/10 speeds can go 2-3-4-5-6-7-8-9-10.
There's no point revving out all my gears in real world driving, I just want to reach the speed limit as fast as possible then go into overdrive. DCTs are very fast at switching into what they think is your next gear. They're quite slow at switching if you want to switch more gears.
For me it's not really about choosing the gears, per se. Yeah I can do that in an automatic, but it's hardly the same. With a manual you get coordination between foot, hand, brain, and you are one with the car. For an enthusiast it matters.
