In this example the price is your guide.

Shimano hubs are really good quality hubs. They are also heavy and can't be changed to any other freehub body. The R 460 rim is a light rim that is still a shallow box section. 32 spoke because Shimano. Heavy build overall.

DT 350 - good hub platform that can be adapted. the rim is a newer design than the 460 but generally in the same class (but better IMHO).

Velocity hub - I do love the company and have done a ton of work with them over the years. Their hub platforms are very similar to what we use at the "house hub" level. Which is to say they are "good enough" for most applications. Will be on the lighter side and can be serviced but finding the parts from them outside of bearings 3-5 years down the road may be a nightmare. Out of all 3 hubs this is the weakest link. As for the A23 - I haven't built with that rim in years. Change it over to the Quill. At 32 spoke you will get stellar performance and this would most likely be the stiffest rim option.

...but what do I know.
