Well, I also have Pete's 53 and 50/50, and like both of them.
Pete's 53 for looks, and 50/50 for protection.
Not that 50/50 looks bad by any means, just that Pete's 53 make's my black metallic ford focus really look wet, and the flake pop like crazy, where 50/50 is less wet looking (but still pretty wet) and more reflective.
For durability 50/50 wins it hands down since for me it lasts at least double as long as pete's 53. (used both on bare paint after a IPA wipedown).
I'd like to ad that XXX-hardcore paste wax that I also have sits perfectly between them in terms of looks and durability despite being their entry level paste wax.
It'll outlast Pete's 53 consistently but not not 50/50 (pretty much down the middle if you'd ask me). Doesn't give a "wet" look, but highly reflective warm glowy kind of shine, Perfect on lighter colors for me since they lack these property's.
As far as application goes it's the hardest consistency of the 3 I have, but goes on the applicator really easy, spreads far and thin, and wipe's off effortlessly (even when apply'd thickly), which is nothing new for me as everything I have from CG does this (and I have quite a bit, just limiting this to the nuba's I have)
Celeste Detaglio and E-ZYME Natura are both on my wishlist, but I'm still wondering if they're worth it...
