Float tube pros: Easier to transport and set up, cheaper. Cons: slow, limited range, you get wet.
Toon pros: versatile, you can row, kick or use a trolling motor, comfortable, carry more gear, sit well above the water.
Cons: can cost 2 or 3 times as much as a tube after all is said and done (even with a "cheap toon", motor, battery, FF, and other stuff you add on), a hassle to set up unless your truck bed is big enough to carry the toon fully assembled. I have a roof rack but its hard and awkward trying to lift it onto the roof fully assembled by myself. and yes, it does get blown around a bit in a good wind, but its worth the versatility.
