Anybody done any side by side comparison of these two products?

I recently tried and liked the 'old' version of Optimum Metal Polish but have been kind of curious about Collinite's Metal Wax. Sounds like it does about the same thing, it's roughly the same price. Difference is I can get Collinite locally.

I, like a lot of you have tried and like 845 so I'm wondering is it worth getting/trying the metal wax?
