You can listen to whomever you want to.
From damper ability / durability standpoint, I would not, from my experience, recommend any of the ones you listed. If I were picking from only the ones you listed, I would only look at the AGXs.
I've been at it a long time, and I know people that are both fully satisfied and fully dissatisfied with an H&R / Neuspeed sport and KYB AGX setup. I know nobody that is dissatisfied with those springs on any of the dampers I listed above.
Make your own call.
And for the most part I disagree with you azian. If I had AGX's on my car, I guarantee you I would be pushing their limits on county road ZZ behind my house. But then again, maybe I drive my car as if I were on a track, so, I will give you the benefit of the doubt in your wording. Still, I don't know how many setups you've dealt with, but AGX's really have the damping power to give those springs an acceptable ride and decent road feel. As for maximizing their potential, sorry, I just don't think so.
