other LSDs are not inferior
a LSD should be purchased based on its use for you
you drift? 2way LSD (brand is your choice)
you drift and f*ck around w/ stufF? like me? enjoy dropping diffs and changing things? SSS is the way
drag/grip? quaife
street stuff? VLSD/s15
street and some drift? 1.5 way/s15
auto x/grip? 1.5 way/s15
etc etc
those above are just MY opinions. but you have to choose what you NEED for what YOU do.
research and education are key
