Darth Maul.

Darth Maul is a highly skilled and experienced fighter, known for his expertise in lightsaber combat and his agility. He was able to hold his own against multiple opponents, as seen in his fight against Obi-Wan Kenobi and Qui-Gon Jinn in "The Phantom Menace". Anakin Skywalker, while powerful in the Force, was still relatively inexperienced in comparison to Maul and may not have been able to match his skill and combat abilities.
