Hope everyone had a good weekend. Was hoping to utilize the knowledge/opinions of everyone here.

A kind soul has offered me one of their spare sets of wheels as a gift to upgrade over my Alex R500s. Problem is, I don't know squat about wheels.

I can choose between a set of Mavic CXP23 rims/Ultegra hubs or a set of Xero Lites (no XR or other model marking)

Both sets are barely used and ready to roll.

For reference I'm 6'2" and 195 and these will be on the "good weather" road bike not the commuter.

Thanks!
