you, my friend...need a brain...lol, not really, nos is alright for a little boost after youve done other work on your motor, but it shouldnt be the first thing you slap on your car when you get it. esp if you're driving a stock eclipse or something like that...
I second that. But I'd get NOS if it was available because its usually cheaper and they have much more stuff. Plus its probably the most common brand so you can get help easy.
I have heard that NOS doesnt meter the nozzles too well, so if you really want a 150 shot, you could be gettin a 250 or even a 75 shot, but not with NX.
