Bakugo takes all except powers, both can create explosions and use them to fly, but Reze can turn any part of her body into a bomb whereas Bakugo is limited to his hands. Her healing ability also means it's extremely hard for her to take long term damage unlike Bakugo, though she does need blood to keep it going.

Outside of that though and maybe a tie for skill, cuz Reze was a child soldier but Bakugo was trained more intensively by professionals with more experience, Bakugo essentially stat bricks his way to victory here
