From the full Exotic Review
"You’re going to be less effective in PvP using this, and the exotic perk will be especially lackluster. If you have the chance to kill two enemies in one magazine you’re probably too close, and they’ll react to you with a swift shotgun blast in your direction. The Zhalo Supercell is a brilliant PvE weapon, as you can essentially disregard its somewhat average base stats, throw caution to the wind, get stuck into hordes of enemies and shock them to death. The Arc damage is useful for burning through Captain’s shields or for Omnigul strikes. Not to mention it is one of the few Year Two Primary weapons with a burn. Overall it’s a great gun to use with unique perks, and it fulfills a role that is good enough to see you use this exotic in whatever activity you choose, so long as it’s PvE. Don’t take it into PvP."
