I've used both. I prefer the foam flag just because it's a simpler design, but for traveling if you don't want to rent a flag, the inner-tube type is much easier to fly with. For those, I'd suggest something similar to the yellow "Diver Down" one because it is more stable in the water than the teardrop style so there's less chance of it flipping and losing the actual "flag" part (yeah that's happened to me too).
