I have Di2 on my race bike and I must be in the minority but when I replace this bike it will be with 11sp Mechanical Shimano.
Initially I thought WOW, this is great. Since then I have grown to dislike the lack of feel in the buttons, its also heavy compared to the current mechanical equilivants.
I do like that you never have to change or adjust cables and you don't have to do any manual trimming on the FD which is about the only benefits I can think of. The battery placement is plain ugly unless you spend the money to have it fitted inside the frame which then adds charging complexity unless you goto the further expense of an external charging port.
Yes it will change gears under a lot of load but this isn't something I do anyway, and if done it is at the expense of your driveline components.
Overall for me anyway electronic is hardly a game changer, it offers no performance advantage and given the price premium over mechanical with limited resources I'd put the saved dollars into other components like a better frame/wheel combo.
