I've owned both. The Jetstream is a better soft shell in almost every way I can think of other than (maybe) warmth. I don't know if one is more popular than the other, but certainly the economy of the 90% jacket could play a factor in that. The Jetstream is better ventilated, much less bulk, cuts the wind better, and sheds water better. I don't know how the weights compare, but I've got to believe the Jetstream is lighter and I am certain it packs down smaller. With a puffy underneath the Jetstream, it will take you late into the season provided you are not sedentary. I'm not sure which jacket is quieter. I guess I never really noticed either in that regard.
We don't get a ton of rain in Wyoming, so I use a softshell a fair amount with that Cabela's space rain gear in my pack. If you get quite a bit of rain where you hunt, I'd expect that you wouldn't use a softshell as much and just use a more substantial rain jacket as your outer layer.
