I have never seen a STOCK subie do what a stock jeep wrangler can do.
I went out to a rutted mud hole in in my then unlifted, unmodified, 89 GLturbo (4EAT trans) with a friend in an 88 Cherokee (same engine, tires, and axle as the Wrangler of the day, coils in front instead of leafs)
I made it through cause the Wheels can drop when the belly hangs up.
The Jeep didn't cause his axle was grading the hump in the middle of the ruts.
Had to pull him out. Both cars had AT tires.
Moral of story........Independant suspension is better in ruts and mud.
Straight axles are great for crawling but not so much for rutted, muddy roads
