I have (and continue to use) OCW and AW. I'm not much for a Griot's user so I can't comment on their product.
OCW - I use it as both a stand alone LSP on quick details, or a booster after a rinseless wash on my own car or for a follow-up detail for a client. I would say that OCW definitely has the edge in terms of shine and durability. 1.5-2 months durability is what I've seen.
AW - I use it as a drying aid mostly, and occasionally as a booster for my own car (it's cheaper!). After about a month AW shows no indication of beading.
Both sprays are incredibly easy to use, light mist, work in the product, and buff off the residue. Easy on, easy off. OCW might need to be applied a bit thinner, as I would describe it as being a tad bit 'oilier'.
