Well after less than 900km (bought it July 2017) of using eTap, the left shifter battery keeps draining. I have gone through 3 batteries (2 of them new in the last two weeks). Last one installed new on Saturday July 28th, went for a 3 hour ride on Sunday and now Tuesday the shifter is dead. Will be taking it to the shop this week.

Had a similar issue with Quarq Dzero power meter. After few months of waiting, Quarq finally gave me a new one.
SRAM sent me a new shifter, so far so good after 5 rides...

I've been using eTap Wifli for about 1.5 years now, no issues at all. I recently used a rental bike with Ultegra Di2 and was not too impressed, it wasn't terrible but the shifters feel so complicated after getting used to eTap ;-)

The benefit of Shimano's button setup is that when I shift the front I also simultaneously shift the rear. I don't think that's possible with eTap's two buttons. So in summary I can shift much faster than I can with eTap. There's also the benefit of the increased shift speed with a wired system. A guy on the internet did some research using high speed cameras and he confirmed the shift speed advantage of the Di2. To each and his own...

Yep, I guess that's correct - you can't shift front and back at the same time....however the occasions when I need to change front and back at the same time are so rare I've never even noticed this as an issue.

I've also heard/read that eTap shifts a bit slower than Di2, the fact that high speed cameras were required to capture the speed advantage suggests that the difference is not all that great :P

How do you manage the shift the front without corresponding shifts in the rear? A shift in the rear is needed to maintain the same cadence. Anyways I don't want to start a war between Di2 and eTap. I'm merely trying to point out that each has their own advantages and disadvantages.

Just pedal harder!! Kidding...you are right, that is a pain sometimes :(

I complete a shift or two with the RD just about every time I shift the FD.

It actually is (sort of) possible to, at the same time, shift front and rear with Etap.

Hold both levers (effects front shift), then release one lever but hold the other (effects rear shift, up or down depending on which lever you hold and multiple shifts, depending on how long you hold).

By the time the chain does a rev around the chain rings (and so effects the front shift) the rear shift will be complete. So is done at the "same" time.

"much faster"? irrelevantly faster would be more accurate

as above, it's possible to front+rear on etap within a short period

My fingers are so fast, I can give the commands for simultaneous FD+RD shifts quicker than the FD is able to complete it's shift. I'd quess it is pretty much the same for Di2. So not much performance is lost, but of course two button pushes are always marginally easier than two + one.

I have owned both Ultegra DI2/ Sram Etap and SUper Record mechanical. Maybe it would matter for some pros on the final 3kms of a race for mechanical vs electronical.

But Etap vs DI2 the difference is really too marginal.

Which do you prefer? Thanks

For the moment I sold the etap(which was on my gravel/cyclocross bike) to install my SuperRecord 11 from my roadbike. Want to upgrade to Super Record 12 on my roadbike.
So I would say I prefer mechanical but it's just that I like the feeling. Otherwise I would say Etap is the way to go. No cables, easy install no/low maintenance and I like how it looks.
