I can't give you a review on the models you are interested in. I can say I have a new set of Kumho ASX's and I am quite happy with them. They are alot quieter than the Bridgestone RE050's I was running before. They handle great. I would not hesitate on buying Kumhos again.
+1 for Asx's. I have them too. they are cheap and perform pretty good for the price.
