I think the FBM is at most 10% better than the Dogfather and that is in edge retention and corrosion resistance mostly. As far as impact resistance and springyness the dog is probably very close to the FBM. I like the RES C handle much better as well. Rust is not a big a deal on a coated knife.
I am really looking forward to the bowie as I don't have one and have always wanted one.
