IMO, both PU super grips are fairly tacky and not too bad when wet. Just remember, everyone has their own opinions about their badminton equipment. Why not buy one, or a couple of one of the PU suer grips and try it? It won't cost a lot and you'll be able to find out whether YOU think they're good for sweaty hands or not.
Karakal PU Super Grip is the original! APACS Super PU is the cloning! Just like Yonex rackets and APACS clonings
also think about towel grip. imo a much better solution. plus, it could be more cost effective as well.
between the two, i will go for karakal pu super grip. some advices in prevention of slippery grip, here is the thread.
When towel grips get sweaty, rackets can go flying out of your hands so you have to be careful with that. I'm sure someone on here has a story about letting a towel-gripped racket out of their hands and it shattering on the net post. Maybe they'll post.
I have very sweaty hands and I have tried both kinds of grips and I find that Karakal ones are much tackier and stay so for longer. Unfortunately, no one sells them where I am so I have to ship them from overseas =(
I have sweaty hands and the Apacs are fine for me. Though the colour rubs off on your hands. I switch between towel and the PU grip
