I haven't popped up from a knee paddle, but I imagine popping up is more efficient from a prone position. At least it seems like a prone popup would be easier (more natural) for me.
I dont think you knee paddle catching the wave, just in paddling out.
Most people seem to feel that prone paddling is more efficient than knee paddling (ie uses less energy) but knee paddling gives you more power and more glide (but uses more muscles/higher effort). Arguably if you are just paddling 50 or 100m out to the line up, this wont make a huge difference, but over a few hours it might.
Prone obviously reduces your wind profile and long distance paddlers (not surfers, but those molokai guys) often prone upwind and knee downwind because of this. Prone is also more stable, which might not seem that important but for surfers paddling out through white water etc it can be quite useful; and allows greater board control. Finally, knee paddling can dent your board (a lot of weight going through your knees) and some boards arent build to be very effective with all of the weight in the middle rather than spread out (vs: when you are standing, yes your weight is only on two points of contact, but they are a few feet apart (no pun intended) and you can change your weight back and forth as needed).
So, in summary: knee is more powerful and greater effort and if you are fit enough and your board is fine and you are stable enough, its probably 'better' overall. But there is a reason almost everyone prone paddles - its less effort, more stable, greater board control etc. And its easier to learn.
