I would rank KW at the very top end of competition suspension category.
In fact most of there stuff is not for road use at all. No other coilover setup I have seen from HKS or Tein has anywhere near the technology when it comes to valving, fluid dynamics and of course the long lasting durability of Stainless Steel. SS was a must when I chose coilovers for my IS as the mag chloride here in CO eats aluminum up anodized or not. I would say that since they primarily deal with German cars however, that they are not well know in the japanese car aftermarket.
One other thing that I like about them from a supplier standpoint is that they offer a bunch of different spring rates and can setup a custom order pretty readily. So you are not bound to what Tein or HKS felt where the best springs rates for your style of driving.
On the other notes, I am hoping to get into the exhaust next week. I already have begun my intake, which you guys should really enjoy once I am done.
