I also prefer the SRAM interface. However, in terms of build quality and smoothness, Ultegra DI2 is above SRAM Force, and that's why I stay with Shimano. I also prefer the fact that you can just plug the bike so it recharges the hidden battery, while with SRAM you need to remove 2 batteries and recharge them (and more often than Shimano). Shimano is also generally more expensive, but man, Ultegra and DA are pieces of art.
Never tried SRAM Red, though!
