Cables are the weakest part of the shimano shifters IME, I just had to change out my cable after ~6000km on a brand new brifter, it had started to fray and would stop shifting onto the smallest sprockets, I was glad to get that warning sign before the cable broke. ...

My preference for cables is that I can fix that.
On the touring board it has also been commented that Shimano brifters go through cables faster than you would expect. I have never used Shimano brifters, I have two bikes with Campy brifter in back, one bike with Campy brifter in front. I have not had any cable trouble but it makes me ask if anyone has an opinion on those for failure modes?
My derailleur touring bikes use Shimano bar end shifters. I am quite happy with them and my hands never get that tired, but I am probably riding one third or one fourth as many hours in a day as you on PBP, so that is not really a fair comparison.
