What are you all actually looking for in the coilovers?
If its speed, i can guarantee that a good driver in a standard 182, would be faster round a track than a poor driver on AST's... instruction would be far more sensible.
If its feel, how can you consider the options, without trying out a few kits first (as mentioned by Warren). Some people prefer understeer at the limit, some over, some neutral, etc, etc.
If its simply looks your after, buy the cheapest available.
AST's are currently well regarded (prob as they are priciest) but people always used to w*nk over H&Rs, it is simply the latest fad.
People on here dont like GAZ, but other forums love them, maybe as they can be re-valved/sprung to your own individual requirements. Strange as it may seem, from a 'proper' (re racing) suspension perspective, AST are one of the cheaper brands when compared to the likes of Intrax, Nitron, Black Art Designs, etc.
