Di2 - IN MY OPINION, and for the 80?? (can't remember - 8020 ?, 8050 ?) group I installed 2 years ago, shifts quicker, quietly (well except for the front cheep), and more reliably that any of the Ultegra or 105 mechanical groups. All of which were installed correctly and in the beginning, needed no maintenance. Which seems to be what the majority of users on this thread report as well. It's not about maintenance though I would change my comment to just state "better".
Ah, yes, the "
appeal to authority" fallacy. Even if you do have more experience than me (and we don't know if that's true!), it's still a logical fallacy.
Again, I am not fundamentally disagreeing: I like Di2 and will buy it (or the next iteration) on my next bike, most likely.
