I too like all three groupo. Once you get near the top of the groupos, it is all good. I would like my next groupo to be DI2 or EPS but Campy did somethings with EPS that I don't like. With Shimano, the battery can be removed and charged. With Campy, the battery is hardwired to the bike. With Campy you can jump multiple cogs but I hear you can do that with DA9070 too. Plus, Shimano is cheaper at least the electronic versions.

I think I would buy DA9000 cranks and brakes and buy Ultegra DI2 for the electronics once Ultegra goes 11 speed which probably won't be until late 2014.
