I own Storm, RotoGrip, Columbia, and Brunswick. I haven't noticed any difference in durability of any of them. Some balls seem to die after a while, and I have found out that just resanding with the final sanding (i.e. 4000) doesn't bring them back for more than a few games. You have to take them back to the original grit (i.e. 500) then bring them back up for the OOB surface to last. This is the same for all of the balls I use.
