Evolution 3: About even, holds less paint.
Revolution: Much slower.
Apache: About the same, Fasta may be a little faster.
MR3: Eggy 3, Apex barrel.
VS2: Fasta LED.
Maybe the fact it's a agitator?
Looks (to some)
I got this gun with my brand new VS2. I imediately tried the hopper, but found I couldn't speed test it without paintballs. This is because it uses a strip, not eyes, to sense paintballs. When paintballs go down the feedneck, it causes the hopper to initiate loading. This is a good idea and it seems like it would conserve batteries. As soon as I got to my other house I found my bag of paint. It was half full, but the Fasta was able to take all of it. That is quite impressive. It was able to unload itself with a lot speed and a lot of consitancy. It is very fast and very conistent for a agitator. At Blitz the next day it fired all day with a single chop (or skip in fire rate). It also was pretty sturdy lid-wise, because all the time I played the snake, shaking my gun at odd angles, the sucker did not come lose at all. It is a very good hopper for only $80.
I would say, if you can't afford the Halo with V35, get this instead. It really would be worth it.
