I've not tried them all. The only wrist restrained I've used is purple fur lined at a play party/Demo, which worked ok except they were set up to high for me and some Door Jame Cuffs that did not work for me at all (my review is on here as to why).
I like just a nice black basic leather one. Depends on the feel you want though. Plain leather and fur are different. Plain leather can be very comfortable though. You do not need fur to be comfortable.
The purple fur ones look nice, I like the subtle color and they do look quite comfortable! However, they are not nearly as nice to wash as to wear... just something to keep in mind.
