I personally bought both and I love it. I think either is fine actually since there’s a need to change every few hours too. Both brands are breathable, comfortable, doesn’t leak and fit well. Kotex is more budget friendly since you would need a lot of pieces. It just depends on which quality you prefer for the material used.
I have more sensitive skin, I prefer "blood" cos it doesn't irritate my skin as much.
I used Kotex only and that was perfectly fine for me!
i can wear blood for longer
