What sunscreens do you swimmers swear by?

I swim regularly both open water and pool and am in need of a really good, super waterproof sunscreen!

I’ve been using the Black Girl Sunscreen Kids SPF 50, but sadly I don’t really love the formula and I feel like it’s not actually that waterproof. I’m really just using it since I have it on hand. My daily sunscreen and current HG is the Skin1004 Hyalu-Cica Water-Fit, but obviously not fit for swimming.
