I wouldn't want an autobox on a race track, but 99% of the driving I do - town or motorway - it's the sensible choice. If I lived in the highlands or something I might think differently, but it's pretty pointless having a manual in stop-start traffic.
The benefits are largely theoretical for people who drive on UK public roads I reckon. I can shift 'manually' on the auto just as easily (albeit the changes are slower), so there is engine braking available, or gear selection if you want to hold 2nd, say, through a corner.
I used to be in the 'autos aren't proper driving' camp, but then I grew up a bit. Get whatever suits you, I say, and bollocks to street racers.
