KYB AGX vs. Koni Yellow Adjustables

Just wondering if anyone has these installed on thier cars... heard some bad things about the KYB's, like they wear out pretty quick within a year or so. Also, the koni's have to be removed in the rear to adjust???? just wondering what everyone else thought, or if anyone knows of any others comparable to these. I need adjustables... Hopefully adjustable without removing them... Oh yeah, the springs i'm using are the RS*R Race springs. Thanks for any help.
