I have ZERO experience with electronic shifting. But, I do have 105 on my Colnago CX and CAAD 12. In addition I have older DA on my Masi road bike and SRAM Red (newer) on my Guru Sidero. I love the SRAM Red and am impressed with the lasting quality of the DA which is 15 yrs. old. But....the 105 is as good as any of it. IMO 105 is a tremendous value. I'd be reluctant to swap it out and spend a lot of money doing it.
