I getcha.
Well, I can't help you there, I've only worn the Wasatch (which was quite comfortable) once, out of those up there. I didn't like the overall fit on me at the time (I since have grown to like chest rigs, lol), so I didn't end up buying it.
If I could change your mind, I'd recommend looking into SORD's products. They're a bit newer on the scene, but they have some interesting options:

You can essentially pick and choose your own rig to your own requirements. It's pretty badass. And if you need multiple options for multiple engagements, you can opt to purchase more than one modular element. I've not yet had a chance to play around with their SCS items, but their pouches are pretty much invincible. Just adding another choice for you to pick through in case you can't decide.
