We have the Hankook's on most of our company trucks (save for mine which has a Hercules tire) and neither is a super aggressive AT-style tire. I did look at the Wildpeak's when I purchased my new tires and while they are a more aggressive AT, bordering on MT, they were out of my price range. They do have a good milage rating though, 55k miles which is great for that style of tire. The tire with the highest mileage rating for an AT is probably the stock Wrangler's that came on the truck which is 65k miles.
I ended up going with the Mastercraft Courser AXT which is a 50k mile tire and they were more reasonably priced. They are rather aggressive for an AT, more so than the Hankook (or Hercules). Both the Hankook and Hercules are rather quiet on the road, while the Mastercraft's do have more road noise. But, the more aggressive the tire, the more noise you get. Can't speak for the Falken's but I would think they might have some more noise as well. The Mastercraft's don't have an obnoxious amount of noise, but you know they are there.
They also seem to do well in the snow. We just got our first snow of the year last night and the truck did well yesterday and today.
