I don't understand all the hype around the prowler. It usually does one bullet damage and not much more if target is moving because it fires so fast that the whole burst has shot even before your aim followed, still projectiles are not that fast so they are affected by movement.
I much prefer the model of high damage/reasonable firing rate at mid/long range (but prefer G7 and 30/30 over snipes cause they are too slow compared to their damages, DPS is largely in favor of G7 when you can aim not too bad).
So indeed, Prowler is nice at short range but not much more that a R45 (whose projectile do the same damage, though multiplier in the head is better for Prowler), R99 (which firing rate is superior and is auto allowing you to melt the enemy, while Prowler's bursts are separated by a long time), or even L Star (now that it can be handled and targeted).
Not even talking about Spit...
