Poorboys will win the durability hands down. Pinnacle will look better but I don't think it will out last Nattys. Plus it's hard to beat the price.
I have plenty of waxes if anyone is curious about some: Dodo juice supernatural, Wolfgang Fuzion, Dodo juice Purple Haze, Dodo Juice Rainforest Rub - Golden Edition, Pinnacle Souvern, Obie Dan Chocwork, Obie Dan Sterling (not released yet), my own personal and hand poured Obie Dan Wax, and I think that's about it...
Anyhow, I am a huge fan of the Dodo Juice line and of ODK Waxes. If you are wanting a wax that will just make your car glow, look out for ODK Waxes Sterling. Dans wax is a little bit more "oily" but it truly brings out the clarity of the paint.
