I agree with Taras. I've never seen a study on track hubs particularly, but in general you just have a lot more adjustment that can be made (tuning) with cup/cone systems.
Experimenting with fill rate and lubrication choice is where the (albeit generally small relatively) gains can be made.

In cartridge bearings it's harder to tease out better friction but it can be done. The biggest contributor of drag is the seals. For a track specific wheel (that means, only on a clean surface and no rain/water to deal with) you can remove the inner/outer seal (or just the outer seal if you don't want to remove/service/replace bearings fairly regularly) and that should be the biggest single gain you can do. After that, again fill rate (and the specific type of grease/lubrication) is the next most likely place to see gains. In my experience, ~50% fill with Ceramic Speeds TT grease has been best (supported by the old frictionfacts document)
