Preference to brifters. With a crankset that is MTB (22-34-44) and a cassette of 14-25, which means that every ratio is consecutive and that all three chain rings in the front are sollicitated, it is nice to be able to shift at will. Then again, there is the matter of repairability. In over 10000 km I haven't had a failure but, just in case, you could carry a down tube shifter in your bags for an easy fix.

Those are unorthodox choices but it may help to be aware of such.
