I learnt in a manual Mitsubishi Starwagon (van) on my L's for 2 years and my first car (for a short time) was a manual 1985 Ford Telstar Ghia 2.0 litre. So yes, I can drive manual, but haven't done so in roughly 5 years since getting the auto Corolla and DSG Golf. I did borrow my brother's manual Hyundai Getz for a week when I was getting some work done on the Corolla a a bit over a year ago as well. If I were to jump into a manual tomorrow, sure I'd probably stall it a couple of times, but would get used to it fairly quickly I'd imagine. Every car is different, etc, etc.
Is the DSG perfect? No - because it's a manual with a computer controlled clutch (2 of them), low speed start/stop driving under 20kph can sometimes be jerky, but the only "defensive" speech is just making sure others know it's not a normal automatic with 'tiptronic' selection, like my parents BF Series 2 Ford Falcon, for example. For the most part you get the benefits of manual and the benefits of auto together. I think manual is great for pleasurable driving, but just isn't my favourite option the other 80% of the time. Auto tends to be easier to sell when the time comes as well.
