Ankascrews perform far better that Dyna bolts etc as the diameter is bigger of the steel doing the biting to the concrete. Example a 10mm Ankascrw is 10mm diameter + the threads, a 10mm Dynabolt is only 8mm internal bolt likewise a 12mm Dynabolt is only 10mm.
The kN in both shear and tension are higher in Ankascres than Dynabolts. Trubolts are similar in performance to Ankascrews however you are left with a protruding thread where as the Ankascrews leave only a hole.
