The air blades work quite well; you can actually dry your hands in a few seconds instead of holding it underneath some lukewarm air for 30+ seconds. I never even use them as they're borderline pointless and so damn loud (I dry my hands on my trousers if there are no towels), but airblades work well enough for me to us them.

I can't speak to the other products as I never used them, but air blades really are a big improvement IMO.
