as far as isolation goes, probably not better… cork will transfer quite a bit of vibration into the floor; it’s much firmer than the rubber feet: they should be soft enough that you can almost push the sub around and see it jiggle like jelly
if it’s good enough, great! but better than vibration isolating rubber is an exaggeration
