Best job how so?
Alot cleaner job. The plastic ez can do arrows alot faster but I get a cleaner look (less glue all over) with the bitz. Plus I like to shoot 4 fletch so the bitz makes that easy. More customizing with the bitz. The others are set at certain offset degree. Bitz you can adjust the degree offset.
For me it all depends on the arrow I am using AND the vane I am choosing.
I have two: The Helix (BOHNING) and Bitzenburger
