What is the best name brand of Nitrous.

 

I'd stick with NOS, NX Express, or ZEX.

 

Which brand is the best

 

they are pretty equal. edelbrock, and Venom are good too.

 

really a personal preference. nos, nx, zex, venom, edelbrock all work on the same principles. although each brand carries different type of parts and accesories they all work roughly the same. minor differences in solenoids, nozzles, jet design....etc. if your a newbie to nitrous i personally recomend zex..... if your capable of tuning i recomend nx/nos direct port(only if it fits your needs)
