The new analog sticks feature a concave design with a ring "nub" around the inner outside surface, much better than the old design. This helps your thumbs from slipping off. The analog sticks new design also seems to give you more accuracy, you'll feel it once you play with the controller. I also love the texture of it, the controller NEVER feels sticky or sweaty after long gaming sessions unlike the original controllers. I'm also digging the color scheme (silver/black), has more of a mature look to it, I love it. Overall I feel like this is the best controller Microsoft has released so far.
Kind of wish I waited a little bit longer for the macro to arrive on the new redesigned controller, might end up selling my Viking on eBay for $200, since it is practically brand new and has only been used for testing purposes only.
