The Montero Sport is a chick SUV. My friend had one in high school and he got made fun of till he sold it. The Honda Passport is not bad, but not very aggressive. The Nissan isn't bad and are dependable, but look bleh to me.
I'm not sure if you are going for an all around review, dependability, looks, wheeling ability or power. That changes things up a bit, but typically the 4runner will win.
