I never had the KYB AGX's though, so I can't exactly compare, but the Tokoco's are pretty nice. Easily adjustable (the fronts anyway, I don't have the rear because I like the stock selectability back there, and adjusting aftermarket rear shocks requires that you tear apart the interior a little), and the difference between the settings is very noticable. I've only gone from full stiff to the mid setting, because the mid setting is as soft as I'd ever want to go (I can't imagine what the soft setting is like, perhaps I'll try it someday).
