Hmm. I've had 1/2 of the OP's list. All good.

Frame-wise, the builder and tubeset seem to combine well; i.e. really good uses really good, but the good frame builder can exploit the tubing, whereas good tubing won't elevate mediocrity.

My experience:

Simplex over Suntour over Campy for friction.

Shimano for indexed. Period. Especially 9/10. I will * the 10sp Campy conversion.

Ergo/STI goes to DA7700. 9000 is close, if the cable was direct routed, perhaps better. Centaur 10, first gen, not a bad thing.

Electronic? I yield to Riddle of Steel and my friend Mike who runs eTap. All I have is Mektronic, which is mostly a mystery to date.

I appreciate what Mavic has done for us, and Continental, and Brooks and VO and Phil.
