^ you do realise Atomic make armada skis right?
Overall they are fairly different skis. The punx are narrower so faster edge to edge and they also have alot more pop. But because they are narrow you have to be more precise on them.
The Thalls are good too, they feel softer to ride and the wider waist makes them feel more stable in slower jib stuff. I have both skis and honestly I prefer the thalls.
But, and its a big but, the imfamous is better then both. So if you dont mind waiting, wait untill next season and get the imfamous. They will be a price point ski so probably not far off what you could get the punx or thalls for now.
