Opinions on Flashes vs. Conussions

I think concussions are far superior.

The enemy is completely immobilized and has a huge sensitivity penalty. Flashbangs turn their screen white and that's it, they can run away or whatever.

Flashbangs also air burst which makes it impossible to throw it as far as concussions.

So concussion immobilize, slightly blind (disorient) and don't airburst while flashbangs just turn their screen white. Anyone else ever think that flashbangs are underpowered? I'm going for the flashbangs calling card and it's just frustrating not having the easy kill that a concussion would give you. I know a buff won't happen but I thought I'd see your opinions on it.
