Its really personal preference...
if you have a 4.7 in the crawl box and a 2.28 in the t-case then its going to basically be the same thing as having a 4.7 in the t-case and only 2.28 in the crawl box.
Only reason why i'd go with it in the t-case is so that i've got the option of going 4wd high in the 4.7 case.
