No, slightly worse which is why I run 2.3" HR2 rear, DHF front on my Bronson. And, FWIW, the DHF is one of the best controlled braking tires on the planet along with it's cornering prowess is why most DH racers are on that tire.
Keep in mind the first Bronsons were shipping with the 2.4" HR2's with dual ply sidewalls which are boat anchors compared to the 2.3" single ply HR2's which they ship with now (and are surprisingly fast rolling for the cornering grip they achieve). Night and day difference between those two tires even tho they share the same name, thus leading to most of the confusion I see. In fact the single ply HR2's weigh a mere 830 grams which is not weighty for a 650b tire by any means!!!
Have FUN!
