My opinion is Pete's 53. Fuzion is expensive and you can get close to equal looks and more durability at a much better price. You can wax a panel with $1000 dollar wax and a $20 wax right next to it and client will be hard pressed to see the difference if any. If your doing production detailing you can't go wrong with Pete's. Higher end details I would probably reach for a handful of other waxes before I go for Fuzion. (Bouncer's Vanilla Ice, Collinite 845 with Marquee over the top. Just a couple that would out last Fuzion.) Besides most are putting wax over a sealant anyway so there is your extra durability you would get from Fuzion.
If this is your personal car usage only. Get the Pete's Most of us are out there washing every two weeks so taking a 10 minutes to put a QD or spray sealant or more Pete's is not a big headache for us detailers.
I don't care how much money you drop on a tub of wax. Shine and gloss come from polishing and wax and sealants just protect. If anyone says any different do your own test. Polish out a spot on your car and leave the one next to it untouched. Put a coat of wax on them and let me know if the wax changed anything other then it got slippery and it beads water now. You can even polish out a spot to perfection have some one else apply wax on 1/2 of the polished spot without you seeing it and let me know if you can tell which side was waxed.
