That's a stretch!
How significant are gear change related power spikes? How much are these effected by whether you have mechanical or electronic gear changes?
Both are small and I'd happily religate the combo to the negligible pile with respect to impact to both pace and leg condition for the run.
I think these seem more like purchase self-justification arguments than actual quantifiable reasons to choose Di2.
