one thing i find interesting about this comparison is the dynotune and the NOS silver one. right on dynotune's site it says "Our nozzles have a chrome Finish and function exactly the same as the NOS fogger nozzles."
yet, they performed way differently. i have them in my hand right now. the dynotune has about a 30% larger (i'm guessing right now) orifice in the jet holder. my guess would be that if i was to swap the jet holder, the NOS Silver will perform about the same.

TOP: NOS Silver
MIDDLE: NX Vortech
BOTTOM: Dynotune
i need a better camera. you should be able to see how each one gets progressively bigger from top to bottom.

in talking with ken from ny-trex when he stopped by, he said when the orifice size more closely matches the jet size, you get better results. here's a list comparing what he said to the first ranking list i made:
same jetting .062/.033 HP
1. Dynotune 423.21
2. TNT 422.52 .093
3. NX SHO 420.06 .116
4. NX Shark 419.37 .093
5. NX Vortech 418.00 .063
6. Ny-trex 415.83 .110
7. CF Predator 412.42 .125
8. NOS silver 403.87
9. NOS Black 389.31
i will edit, as i get the info on the nozzles i do not have orifice sizes for.
