I've kind of been stuck on Gold Tip Ultralites for the last 6 years or so. Prior to that, and still my favorites are Easton ACC shafts. I've also used Easton and Beman ICS.
Frankly I find little difference in durability between any of the AC shafts from different makers. Hit what you're aiming at and they're all pretty durable. Start shooting trees and rocks and they all can crack or shatter.
It's no secret that heavier shafts usually mean thicker walls which leads to better durability, but this can be subjective, too. As far as hunting goes I don't worry about durability. If an arrow delivers a broadhead to it's intended target while flying straight then it's done it's job. If it gets lost or broken then it's just a price of playing the game.
It's the other 8,000 shots a year that I'm concerned about. To that end I can buy half dozen of a given shaft and still have 4 of them left 5 years later. Reason being that I do not shoot groups. No reason to smash arrows just to prove I can.
