What do you like? More importantly what don't you like?
Note: if I run Red I"ll be using the Exogram crank, if go DA I'll be using an SL-K crank. Both options will be running a DA cassette, and KMC X10SL chain.
The group is spot on, my two other bikes have force and ultegra, the front shifting is nowhere near as good on the either. You can shift to the big ring going uphill with no problem, I haven't felt completely comfortable doing that on either of the other groups. Rear shifting is comparable to force, snappy, loud and precise. Either you like it or you don't.

Yep, completely fine with the Double Tap. Come to think of it I switched from XT thumb shifters to GripShift back in the day and never looked back.
I really like how quiet the SRAM combo is with red cassette and 1091r chain. I had a 7900 cassette and KMC x10sl TiN chain but switched back to the SRAM due to less noise. The 7900 chain runs quieter with praxis rings and 1050/1070 cassette but I've found best results with all new RED when using the exogram
fast, straight on, light
crappy front derailleur if you don't go steel
love the front derailleur as it is so stiff and good, gears really soft
slow without feedback
But can also depends on frame, if you got bottom bracket for 24mm it doesn't matter but if you got an oversize like BB30, PF30 or OSBB Red has an advantage with the crankset with any need of strange adapters and extra weight.

Mix-match-compatible (for the most part, it's relatively friendly to mix years/levels/components, including SRAM's mountain range if you want to do something unique)
Light weight ; Fast gear changes ; Double-tap shifting. I love it. It's personal preference, however ; Adjustable reach on the levers, for people with small hands. I don't use this function, but know people who do ; Very tunable. It might be a combination of availability, comparatively-low price, lack of 'auspicious reverence' for the brand/heritage, or the nature of people who tend to buy it anyway, but it certainly has the greatest amount of tuning done to the its components compared to other brands ; The exogram crank is ridiculously awesome. Possibly one of the best single components I've ridden in the past decade and all the more valuable when I consider the price it sells for.
I don't like their graphics too much. The newer (2012-present) derailleurs have improved. ; The spider orientation of their Exogram crank isn't the greatest, but then again DA9000 went to their own unique BCD (with justification), Campagnolo has had a strange compact BCD for quite some time with little justification, and the BCDs on both the standard and compact Exograms are still industry standard ; You will get a lot of people who don't ride their bikes (seriously) enough whinging about you riding SRAM.
Pro: To be honest, I prefered 7800 over 7900, but it was largely the same. The looks grew on me, but I eventually stopped riding it. The shifting is typically supreme, as are most Dura-Ace lines. I can't really say for certain that any front derailleur was better than another brand because I've found steel-red, dura-ace and record all pretty much equal when it comes to the most basic of the derailleurs: the front. (However their 9000 is a lot like the 2012+ Yaw in having an improvement in the Front Derailleur category.). 7900 Cranks are pretty awesome for stiffness, not so much for lightness.
Their design is very modern with flashes of metal and coated-metal, a bit 'samurai sword' like, which is nice. While not necessarily any more 'strong' than the carbon competitors, the metal components lend themselves to a feeling of solidity and durability. (However, everything in this world will break at some point in some way)
Dura-Ace also seems to be available everywhere, which is a plus. It's not like SRAM nor Shimano are in the way of scarcity (some might say 'exclusivity') that Campagnolo is, but most places will have Dura-Ace spare parts on the ready.
Cons: Heavy - (ier than Red). Expensive. Didn't see too much tuning going on in the Dura-Ace world.
-set up. Some people (and mechanics) will state unequivocally that Red is finicky to set up. I completely disagree with them and found it no more difficult than any other group, and no more or less necessary to adjust/maintain through use compared to other drivetrains.
-Sound. As for sound, that's a personal decision. Some people really love the Dura-Ace/Shimano silent shifting, some don't. I felt the shifting was slower compared to Red, but 7900 felt just a little bit smoother. Red has a very distinctive 'thunk' to it, which I love. While it is certainly a fast shifter (especially in sprinting), each shift has such a beautiful, very mechanical sound to it. Kind of silly, but last weekend I found myself shifting through gears while slowing up for my ride mates to catch up to me while on a double, just so I can hear that sound.
-More on sound: some have said that older Red cassette was loud. I guess so, but I wouldn't really know. I tuned the old OG1090 cassette and made it really darn quiet, quieter than the Dura-Ace cassettes of my friends. I now run the 2012+ XG1090 cassette and it's even quieter.
I have Da 7900 on my 2011 Addict R1 and 2012 Sram red on my Cannondale EVO with the steel front dr. I do like the shorter throw on the red shifters, however would not trade one for another. My Cannondale I call my weekend Century hill climber and the Scott is the group mid week throw down bike.
