Welcome to the Forum!
Tire suggestions are like opinions. Everyone has their reason for their choice of tire. Aggressive off road isn't sufficient of a description for what you intend to drive in. At that size, most are going to suggest either BF Goodrich AT or Goodyear Duratrac. Asking which is better is like asking folks if they like Ford or Chevy better. You will get opinions all day long.
