Is the Nerf stampede overrated

The answer depends on your opinion. There is no "best" Nerf blaster. For example,

I prefer the Raider CS-35 because of it's rapid-fire and large drum, and the Jolt EX- 1 for it's extreme range and tininess. But my friend prefers the Stampede ECS because it's fully automatic and it looks cool. And someone else might like the Recon CS-6, Firefly REV-8, etc.
