Straight axle is much better for crawling. More ground clearance, more flex and articulation, much stronger axles, the list and debates go on and on. You will hardly ever find a hardcore rockcrawler wiht IFS. A few have tried it but end up switching to solid front axle. Most of the toyota guys swap a solid axle into their crawlers. Now prerunners are a different story. An IFS would be better for a prerunner. Go to pirate4x4.com forums and just do a search for IFS and you will find yourself a ton of debates against using IFS on a crawler.
