The wb isn't measurably less accurate,they are measureably less forgiving imo.
I am not buying one to test it.Anyone that has one,purposely torque the grip and see how the poi is affected and then do the same with a prong style or whatever and see how it stacks up.IMO,the dropped arm shot would also be worse with the wb and I KNOW they are not as easy to tune PROPERLY.I have done that one more than a few times.
BUT,that has little to do with accuracy and imo,it is a fine hunting rest if that is what you want to use.But it isn't for me.
I have torqued as crazy as possible out of boredom and saw misses but nothing dramatic (probably a foot or so). I just started a thread on this (How bad are your misses??) I can strangle my bow grip and still be right around the 10 ring consistently.
I have also found mine to be quite easy to tune and stay there........I guess I am lucky.
