If the 10 bolt has 3.73's in it and its in the truck, I'd say run it, unless it has problems somewhere in it. If it has problems and the 44 is sound there is your answer.
The 3.73's you got for the rear, are they brand new or used? I think used gears can be tougher to setup.
Have you considered stepping up to a 3/4t 14bff? Should be able to find those all day with 3.73's in them, and you'll never break it.
