This falls right in with "which wax, polish, sealant, coating is the best". Inexpensive OTC vs. high priced enthusiast products. Then what defines "best"? Cost/value, ease of application/removal, appearance, durability/longevity? And lets be honest, most opinions are truly subjective based on personal experience(s) rather than objective standard testing. And what of the prep work before applying the LSP. It seems to me that a product's ability to stick around (pun intended) is going to be at least in part based on how well it adhered to the surface...which may be [even] more in question for the average enthusiast that reaches for an LSP every third wash or so.
In my 'back in the day' recollection I think NU Finish was one of the early adopters (at least in OTC) of polymer technology over carnuba wax. I think it did have greater longevity than carnuba, but I don't recall it being 'a once a year polish' as claimed. Combined with trim staining, horrible carrier dusting and a god awful smell makes it less than 'great'.
I also think that sometimes good hearted enthusiasts can unintentionally become product snobs. Some of the more expensive enthusiast products are great, but many are only just as good, but cost more. One good experience (or one bad one) tends to dictate our opinion, potentially slanted to the side of unfairness. So some specially products are great, others not so much. The same holds true for OTC products. We all find our way and champion products we've come to believe meets our individual measure of 'best'. For some it may simply be depth of shine, others may be application ease, or durability/longevity, or price/value or any combination. Lets face it....we want it all, but I wonder if we ever really get it? If there was really one 'greatest'....we'd all be using it and end of debate!
