Suggested by iKnowledge Ariel was very talented as a mermaid. She can swim quite fast and that’s always useful in a fight although on land she is quite average. Meanwhile Raya is a very talented sword fighter who is used to a combat setting. She has more experience than Ariel and will be able to win this one more times than not. It’s hard to just jump into a battle when you haven’t been in the ring before. Raya wins.

If Ariel has all her composite powers and abilities, then Raya’s chances shrink. But factor in Sisu, and it could be better than you think.
Yeah Ariel’s definitely had some pretty good abilities so this wouldn’t quite be a stomp or anything like that
