I used to swear up and down that I would never get electronic shifting because mechanical shifting has gotten so good. I am warming to it for my next bike since everyone I know who has Di2 loves it. I am also sick of changing internally routed cables and Shimano shifters eat through a lot of those.

If I were to go electronic, I would go with Shimano Di2. I have heard too many stories of broken battery tabs on SRAM eTap.

If I were to go mechanical, I would go with SRAM as I am sick of how often Shimano shifters eat cables. I now have SRAM Force 22 on my road bike.
