Azenis and Hankooks are very close competitors, and I used to recommend both. Now, however, I'm pretty set on BF Goodrich T/A KDW 2s as street tires. Only things I hear about them are excellent, and for around $130 a tire they aren't a wallet buster. If you are looking for something a bit cheaper though I also still tell everyone to try Kumho Ecsta MXs. Had a friend run them at Sebring this past weekend. They are excellent street tires, fairly good in the rain. He said when they heat up on the track they become fantastic. Most street tires maintain a similar grip level when DDing as opposed to hard driving, but apparently the MXs go from excellent to superb.
