Now I'm not sure if either is 'better,' but I've been doing just fine with the 122. The 100mm snipes better, that's for sure.
I found the 122 to be inadequate at long range, equivalent at medium range, and superior at close range. That change costs 85k for the gun and 1k for each AP shell. Too me at least, the credit cost isn't worth it.
