Neocork has been great overall, it just lacks lugs for extra traction on certain surfaces. I find both to be extremely comfortable, but would not take my Indies with neocork out in packed down snow or wet grass inclines. That said I have taken neocork soled Indies out on many hikes, and that includes full submersion on river stones with rushing water and have been fortunate enough to not bust my butt yet. I absolutely prefer commando for a boot whenever possible so I don't have to worry about anything. Both of these soles far surpass Dainite in my personal experiences though, which is like walking on ice when on slick/wet surfaces.
The problem I have with Commando is that the sole is not very robust.
The stitching comes undone or the thin rubber can tend to break around the toe.
