I just took my truck out for a spin on newly wet roads and made a hard acceleration from a right hand turn with and without 4Auto engaged. 2wd with antislip spun, but still moved the truck quickly and traction control limited wheel spin. In 4Auto, nothing slipped, it was glued. This was pretty similar to my experience owning a 2014 wrangler without antislip and in 2wd (would basically stand still on wet roads making a right turn) and my Jeep Grand Cherokee with full-time 4wd which was always glued to the road. In my experience, it goes 2wd without antislip, 2wd with antislip, and the best is 4auto. Ram and GM offer the 4auto with (I think) every trim, and Ford doesn't offer it until the Lariat. Long story short, 4auto is the best, but for those that dont feel comfortable leaving the truck in 4auto all the time, antislip is a must.
