Who is the better swimmer? (Patreon)

It's been a while since I've done a poll so I wanted to throw something up for fun!

I was curious who you all thought was the better swimmer between Sabrina and Ariana.  Both of them have the exact same amount of training and they have very similar builds as well.   If you have some reasoning or head-canon, feel free to share in the comments below!  

If I like your reasoning, then I might make it officially canon!  Though it would have to make more sense than my own head-canon, which I won't share here to prevent influencing the poll in any way.  This isn't going to play any major significance to the story, but if I like someone's answer enough,  I'll try to work it into a conversation somewhere.

Much love!
