Can Any One Tells Me What's The Benefit In Using Shave And A Haircut Tool

[jefferyqi]

I have not experience in Shave And A Haircut tool. I only use Maya Fur system to reach the effect. Can any one tells what's the advantage of Shave And A Haircut tool? Does it looks more real than the Maya Fur System?

Fur makes fur, shave and haircut makes hair.
