I much prefer eTap to Di2, it works a treat and is so easy to setup. Only had one battery mishap so far, when I rode the bike for the first time in over a month and the front derailleur battery was flat. Have been running it for nearly two years now and still haven’t had to change the shifter batteries.

Di2 works well and is easy to setup too. I've run batteries flat on Di2 (literally this morning, in fact) but just plug them into external battery or dynamo USB on the move and charge. How big is the SRAM charger? They reckon the deraillers get 1000k which means quite a bit more charging than my Di2 setup during ultras. CW said shifting was slow - did they fix this with a firmware update or something? Do they do TT shifters? How much did you pay for yours?

SRAM? Don't know enough about it to dismiss it totally but I already have plenty of experience with Di2 and know it works well, have existing parts for Di2 and I don't need to be carrying MORE spare batteries for a ride and their charging dock. I feel dirty enough just using one of their cassettes...
