In the Rage Burst Thread I posted one example what you can do with the Deceptor:
Here a short picture story what I’m able to do with Rage Burst, maybe someone found it interesting or helpful. A Lair mission and at the start of my first turn one of my Assault/Infiltrators spots a Chiron and close behind him a Terrorsentinel. My Heavy has jumped in as close as he can, not enough to get line of fire, but lets see this situation first:Lair Rage Burst 1

None of the other weapons you mentioned above is able to do something like this. Yes, you need a bit of luck like me in this Lair, but trust me, this is by far not the only situation where I learn the Pandas to fear the Deceptor
Best result was a RB on a Scylla with over 2500 damage, for sure with sneak attack (max possible with sneak attack, strong man and reckless would be 60 x 87 = 5.220).
