Yes, the 10-bolt is similar to the Dana 44 - it is a cheapened version with lower quality materials. It is common for the diff cross pin to elongate the holes where it passes through the carrier. Also, the tubes have a tendency to loosen and seperate where they are pressed into the carrier. I haven't witnessed the tube thing firsthand, but have seen many, many slopped out cross pin holes. I personally hate 10-bolts. On the other hand, the 14-bolt semi-floater is as good as it gets (GM-wise) without going to a 14-bolt full-floater, which is very different but also quite good.
If it were my money, and the axles weren't under an otherwise nice Sub, I'd use the what you've got for now, and start looking for a Dana 60 and 14b FF to swap in later. Same bolt pattern, spring spacing, etc. so it would be a very easy swap down the road.
