I haven't used Di2 personally but I've been keeping a keen eye watching it in our group rides and have to agree, it doesn't seem any worse or better than mechanical... at least the higher end mechanical groupsets.
I wasn't sold on Di2 when I built my bike last winter and passed on it since it literally doubled the cost of the groupset, it was an easy decision. Admittedly I haven't looked further into spec sheets to see how it saves weight, makes the drivetrain more efficient, or adds reliability. It must do one of those, or all 3, because the stuff exists and at a dear price. I think ignorance might be bliss for a little while longer lol.
