Tire diameter plays the biggest role in determining what gear ratio. There are several other factors to consider as well. What size tire are you running?

That front 44 will fight admirably, but won't live for very long with the 44"+ tires I'm assuming would be 'appropriate' for a truck with a 25 inch lift. I'm thinking of that moment when you're pegged at 4000rpm in the bog, spinning the tires, and then all of a sudden the front tires grab on relatively solid ground on the far side of the hole...

When you say 'mud truck' I think big lift, big tires, big HP - as in the kind of big tires and big HP that are probably pushing the limits of a Dana 60 while being thrashed through a bog. I think the bare minimum for a mud truck would be an Eaton or 14Bff in the back and a Dana 60 in the front.

Aren't there companies making stronger u joints and axle shafts than what was stock in a 44? Most of the time when a axle shaft/u joint broke in my 44s was when I was pulling some other stuck guy out and I was in reverse pulling them from behind. Once I realized this I never did that anymore. I turned around and hooked from my rear.

Yes there are, but the carrier is only going to take so much of a beating, not to mention tweaking the axle tubes under heavy load and a bad bump......
