My new bike is new Sram Red and I wish I went with older red Black edition. IMHO the diff between the new Red and older red is not worth extra $. My old Red (now on the rain and travel bike) is working perfectly (all Red with FSA cranks + PG-1070 cassette + KMC X10SL chain) - superb shifting. I started considering electronic. Ultimately I'd go campy but EPS is still not rock solid. I never was a Shimano guy but if I can get a great deal on 9070 I'll switch and later will consider either EPS or maybe whatever SRAM will come up with. I still love my Red but it's not the new Red.
If you don't think New Red is considerably better than Black, then you should know that Force is actually as good as or better than Black! The only difference between 2013 Force and Red Black is that Black is a very small bit lighter and has infinitely worse front shifting. Force got updated this year with ZeroLoss on the rear shifter, Black's chainrings, and ceramic pulleys--the only places where it was actually worse than Black. Black is kind of a crippled lamb right now and they'll probably put it out of its misery soon. For SRAM, the choices are new Red or Force, and Red's definitely got a few points going for it.
I've been very happy with Force was able to make the three changes from 2013 for under $200. The price jump from Force to Red is pretty steep, but the yaw FD, updated hoods, and chainrings are very nice and the brakes are absolutely killer. It's also hard to argue with the lightness.
