I looked into this while being seduced by the Planet-X titanium DA or Red builds. As you would expect its a bit of a personal taste thing, although a few points I noticed were:
The rear mech of the Red group is sometimes claimed to be a bit flexy, affecting shift speed - This was a non issue for me as I would'nt be racing.
The front mech of the Red group is often swapped out for a force mech by racers due to a dislike of the flexiness.
The Red group is lighter.
The Red group comes with ceramic bearings as standard.
The new shape DA levers are very comfy to hold. This swong it for me as I would looking at long hours in the saddle.
I read good point regarding the ease in which you keep shifting with the Sram levers while moving from hoods to bends (good for sprinters? I would'nt know).
The new DA cable routing is not universlly popular. Demonstrated by people like Hushovd using the old levers in the 2009 TdF.
Most of these considerations are non-issues for non-racers though. I would have gone with DA in the end, as it would possibly offer more comfort and reliability. Probably barely any difference though.
