Is there any reputable data that shows one wheelset to be faster than the other? I've read through part of the Hambini s&*$%show thread (as much as I could stomach) and place exactly zero credence on any of his data.
Other deciding factors? Anecdotes I've read here seem to indicate that folks like the Enve hubs better than the Zipp hubs. That's tempered with stories of Enve rims delaminating if run tubeless with the wrong rim tape (yikes). Overall, I'm struggling to choose one over the other based on anything other than aesthetics and/or perception of resale value (not a big deal to me as I plan to keep them for a while).
