For those of us wanting to maximise miles and tier points/status credits this is like Lesson 101. You never choose a non stop option, instead you work in as many sectors as possible and exploit the sweet spots. Ideally yeah, with shorter transits but you can't have it all.

I could fly CMB-CDG non stop and get 140 tier points. Or, take the OP's itinerary and net 320. Easy choice for me!
