His semblance is likely being able to "charge up" his weapons attack power as seen when he demolished the spider droid. I would neccessarily call it a better semblance. It's just what his semblance is. Weiss's glyphs may actually prove more useful/powerful.

It could also be a matter of training. Adam may have such a powerful semblance because he's trained himself into mastering it. Perhaps Blake's shadow clones or Pyrrha's magnetism have hidden potential they just have been able to tap into as of yet?
