I have had both, and the Axis. The Guide shed water well for me for a while, but not the wind and it fit oddly. Kinda tight in the chest, yet baggy and long in the arms. It breathes well. The Jetstream is a good jacket, blocks the wind really well and sheds water as good as the Guide at least. I feel it's slightly warmer if there isn't much wind to block, much warmer if there is. I don't think it breathes as well as the Guide. Very comfortable. One last thing on the Jetstream - the one I have is a solid color (black) and the face fabric is super loud and seems very different from the face fabric on the camo versions that I have seen. I couldn't use it for any serious hunting, it's that bad. Not sure if the other solid colors are the same or more like the camo versions. Honestly though, it's a great jacket and I know a lot of guys that love them and I think it's better than the Guide overall.
I like the Axis best of the 3. Lightest weight, breathes well, sheds wind/light moisture really well, good fit, cuff cinches, my favorite collar, I like the higher pockets (some guys don't), quiet enough. Used it a lot this last season and was impressed.
tl;dr
Guide - gone
Jetstream - my general purpose outdoor jacket
Axis - my hunting softshell when I use one
