The 9 bolt is stronger than a 10 bolt but parts are harder to find and are more expensive.
A 10 bolt can be beefed up to take a lot of abuse. I'm still running a 10 bolt in my race car.
Swapping them is easy. All third gen f-body diffs are direct swaps regardless of if they are a 10 bolt, 9 bolt or the rare Dana 44. External mounts are all the same. There are slight differences in castings, axle sizes, gear ratios, disk or drum brakes etc over the years but they'll all fit. You can even install a diff from a fourth gen but it'll be 2 inches wider on each side so proper offset rims are required.
