I have the Simms G3s. Have no experience with any of the others, so I can't compare. But I love the G3s. They fit well and are comfortable. Have a wide belt with a sturdy plactic buckle that's completely functional. They have a fly and waterproof zipper which makes them true pants rather than waist-high cutoff waders. (Had some Cabelas waist-highs that I hated.) Down side is the cost.
