Gimli > Legolas
Legolas sucked in the movies. With his womanlike physic, supposed Omnipotent "Elf Eyes" and the whole Deus Ex Machina power, he STILL couldn't kill as many dudes as Gimli. Legolas failed on every level. He was much better in the books.
Hell, he wasn't that great in the books either. Tolkien even said he did the absolute least out of the entire Fellowship.
