In my opinion build quality is number one, machine built are massively inferior to a good wheel builder and one or two professionals are a class above.
Then what the wheel is built from, 26 is stronger than 700, but loads of spokes mean a few can die and you don't need to worry, spoke type and rim strength. All these things are interrelated, your wheel is only as strong as the weakest part of it.

Who the hell dishes a wheel for polo anyway?
