I think it really depends on your driving habits, or rather, style/use of driving.
If its a daily driver and you live in the burbs, I think a 6MT would def be the way to go. If you live in the city with constant traffic, the DCT would be great.
I ended up buying a DCT instead of a 6MT after driving a friends SMG M5, just loved how it felt and you still have the shifting capabilities.
It's really apples to oranges, it's one's taste.
