Comparing di2 to mecanical is apples to oranges. preferences are personal. Really depends if you prefer the simplicity of mechanical or the techiness and shifting ease of di2. personally i like mechanical. electronic is anathema to what cycling should be in my book. others will of course differ. But in any response you are inviting that bias.
+1. I have both. And I could live with either system. I get occasional mis-shifts on my mechanical group but it's not like it ruined the fun of the ride.

I think what makes the decision so difficult for the OP is that he's comparing two systems that roughly costs the same, and each system has its pluses and minues :D
i was biking in france this sept and someone on a new di2 bike had a shifting failure nobody could figure out for a few hours. turns out a connector got loose. i'll stick with my 9000 mechanical. you can laugh at this , but this stuff does happen
Once you figure out what it is it's not exactly hard to push the cable in. When you think about it, the solution is a lot easier to fix than mechanical.

Be careful combining the DA 9000 crankset with the latest Di2 front derailleurs. They aren't made to work perfectly together. Different spacing.
I have this setup on my road bike and works just fine. Shimano says that they're compatible. Compared to 9100 the 9000 big ring is in the same spot but the small ring is only .7mm from where the 9100 is.

Is anyone with an R8050 front mech able to measure the height and depth from the clamp bolt for me? I can't get the etap front mech high enough on the ViAS to run a 53t Q-ring and am tempted to sell the Etap and put R8050 on it
