Not even close imo. Avenge when it came out was actually criticized for being not good enough. I always felt that wasn't the case. But avenge can be easily played around and silence was more proliferate so if you could manipulate avenge to drop on the right target, you could get double value off your silence, cancel avenge and silence a target you would silence anyway.
Just the fact you can play around avenge makes it weaker than say a powerful curve card like muster, which is both great on curve and later in the game as fuel for quartermaster.
