A truggy is definetly durable, unless you hit a tree at an odd angle and then the long arms put a lot of force on the hinge pins and could sheer the aarm (my experience with my X1-Crt anyway). The ground clearance isn't a problem in my experience as long as you carry enough speed, you can bash and smash through anything. The only thing that breaks it are very solid objects, even these aren't a problem if you center them with the bumper. X1 or X2-crt gets my vote.
