Depends on what you like.
Stretchier wraps can be jacked way tighter, and can be great. Examples are metal black, and APT blue mamba
My personal favorite for a long time was convicts... they were great. Easier to wrap on your own than strangulators...
My new favorite is strangulators... You just have to know how to wrap them. I probably get close to 100lbs from them...
If you can deal with the pain the old style TP5000 knee wraps were supposed to be the best, but they changed the material so I don't know now.
As for all the wraps I have used-
Blue mamba- easy to wrap, stretchy, if you jack it as tight as possible then it gives great support...probably got 65lbs from them
THP- Stiffer, uncomfortable, easy to get tight, good wrap, probably got 65lbs out of them
Convicts- Stiff, great wrap if you know how to wrap it- got about 75-85lbs from it
Strangulators- AWESOME. I get close to 100 from them
Metal black- they are ok, but I like stiff wraps... they have good pop, I probably got about 50lbs, but I know some people who love them
EFS Super heavy wraps- great if you have someone to wrap for you, but I can't wrap them properly myself... I get about 75 from them when I wrap, and I can get over 100 if I have someone wrap, but usually I don't have anyone good at wrapping, so I stick with something I can wrap myself
