I've never used knee wraps before.
These are a thick rubbery type material.

Used for first time in competition on attempts two and three
Didn't use in training at all, apart from practicing putting on at home once or twice

Good support, easyish to put on ( getting the last bit tucked was the hardest )
1) 155kg with rehband knee sleeves
2) 175kg with the wraps on tight. easy 15kg PR
3) 185kg with wraps on tight. hard 25kg PR

Going from the knee sleeves to the wraps is a big difference in support
Highly recommended
