I'm not a fan of anything but an oil-based product for decks. Foot and furniture traffic on a latex acrylic (translated: soft plastic) surface is not a long term solution in my view. Look at what d_rek just did with TWP products. His project is excellent in my view. TWP is oil based, and the MSDS contains mineral spirits, naphtha and benzene. These are long lasting, high quality chemicals for exterior wood applications. Latex products are sold to consumers as easier to apply, easier to clean up, and likely less expensive, and probably more available on the shelves at big box stores. These situations for me are a pay-for-performance kind of thing.
