I have dual ultimate's in my Tacoma and love it! I wheel in muddy midwestern/southern slop and wet rocks and spend most of my time in 4.7:1. I rarely use 2.28:1, only if i really need wheel speed, which most of the time the 4.7:1 can provide. I love the gear options that having both 4.7:1 and the stock low range provide, i love the crawl speed as well and i would recomend going that route if you have the $$$. My second runner up would be for stock duals.
