I picked up some of the KUU Mach III universal, fluorinated wax when I was in Banff this season, and it has been amazing. It was a little pricy, so I'm not sure if I'll be making that heavy of an investment again when I run out, but man... it's nice.
I've been living off burton rub-on wax the past two years. My board even when i didn't wax after the third trip still performed the same, probably because it was new. The rub-on wax works for a day depending on the weather.
