Well, that's going a bit overboard. Nel knocked him onto his back with Lanzador Verde and then said she wouldn't kill him. We can hardly call that a victory, especially since Nnoitra was able to just hop back onto his feet. Nel presumed that she was still stronger than him, and chose to abide by her morals and let him live. That is what we saw take place. There's no telling what would have happened if she hadn't turned back into a child.

Which brings me back to my point, we don't know if Gamuza has any abilities other than Lanzador Verde. Going by what we've seen alone, then Tiburon is more versatile in every respect.
