I don't think it was mentioned, but the shifting process is different between Force and Ultegra Di2. You should consider whether you like one versus the other. I liked the size of the shifters on SRAM as they are much easier to operate with thick winter gloves. However, I didn't like that you had an extra step with SRAM to shift the front and rear as you can't do them simultaneously. I had Di2 on my old bike and stayed with it on the new one. At this point I wouldn't buy a bike without electronic shifting.
