I've seen very little hard evidence.
Indeed these comparisons, by the difficulty of rigorous testing, are largely subjective. The link provided quotes conditions :
"All shot with a Markins M20 ballhead on a slate floor on a concrete slab foundation, indoors." Which hardly mimics real life landscape shooting conditions under which performance may be very different eg how the tripods vary in response to wind pressure, but provides consistency of conditions. Even the way the legs lock may please some users and greatly frustrate others.
Above it is stated one is worse because the legs flex, do we know if that is actually a bad thing? Maybe the flex absorbs forces better than rigidity? I don't know. Is heavier better? Doesn't that depend on the materials being comparable and even then the construction used?
Total minefield IMHO and the chance of finding reliable hard evidence that mimics the conditions you will be using it under and your equipment and how it is mounted, eg with a particular lens attached the load centre of gravity placement must be factor inn performance, is approaching zero.
My advice is buy them, test them, and decide. Re-sell and consider the loss the price of knowing yourself.
For transparency: I shoot using a Gitzo 3540LS
P.S. I did find another comparison:
