Electronic drivetrains come up pretty frequently when I talk with my athletes and I recently was asked if Di2 was worth the upgrade over an equivalent mechanical shifting groupset.
Fair warning my experience with all things groups is very strong when it comes to Shimano. I have ridden on SRAM road groups and have a Mountain Bike with an SRAM Mechanical group set.

I will share my experiences, anecdotal accounts and industry information that will be useful when it comes time for you to make that all-important buying decision.
