Chameleon coating is more versatile. Camo can work against you (make you more noticeable) if you're wearing it in the wrong environment.
Wall Running and Gliding are both incredibly expensive and the math doesn't really back them up. Gliding lets you run (Magic) meters across an unstable surface, but that's usually a distance that a moderately athletic character can jump, especially with a running start. Similarly, unless you specialize in athletics/running, odds are good you won't be able to Wall Run more than a couple meters, which isn't much of an advantage. Both powers are cinematic and cool but are far too niche and much too expensive to be worth their listed cost. Lobby your GM for a price reduction. Personally, I would charge 0.25 PP for them.
Traceless Walk is also expensive, but it will come up in play a lot more often too. I took it for my adept because I wasn't trying to optimize, but there are other approaches that are equally effective, like Improved Ability - Infiltration, or The Invisible Way + Unseen Hands (from The Way of the Adept).
