doubt that there would be a significant advantage for infi in destruction testing, the S6 still stands as the benchmark in the noss series of metal torture. the sod is very close to the s6 in design.

i would assume infi would have an advantage in rust resistance, edge holding and of course in emptying your bank account, beyond that i've always wondered about the advantages for infi in normal use

does anybody have a basic 7 and a sod, that's a comparison i would like to see
