They're very capable on certain things, terrible at others, and you comparing it to a gladiator doesn't bode well. Jeeps are good at rock crawling and anything that's low speed high articulation. They're awful at dune running, fire roads, paved roads, pretty much anything but rocks. You only have about 5" of wheel travel, so anything needing some articulation is out. The IFS shines at anything with speed (meaning 20mph and up). You'll be fine in mud, some trails, dunes, things like that, but high articulation trails will be rough.
