I have great results with my Bilstein. I have sets of 4600's on my road truck for about twenty years and they've always done a fine job for the low cost.
On my offroad vehicle, I would use a minimum of a revalvable shock. That's a 7100. These are comparable to the lower-end Fox 2.0 (not the higher-end coilovers reviewed in the OP). The 7100's are a great value in a light duty shock. They work great for moderate speed dirt road work that will not see high compression damping. I continue to use 7100 short-bodies for the rear because of limited clearance. I've worked out the valving on them myself, which is quite easy to do.
The 9100's are very good indeed for a lightweight overland and trail rig. I've had no trouble with the finish or rust for about three or four years now. I do not wax or polish, but recommend doing what's necessary for the environment they're used in. These are 60mm shocks, and I would compare them more favorably to Fox and King 2.0's. They are closer to the category of 2.5" shocks. I couldn't say they're better than Fox or King since I haven't used those. I imagine they'd be on the lower end of the 2.5" category, more like the King Performance series rather than the Pure Race, but the prices easily reflect that. They're prices are about 20% lower than the other brands.
