There are many advantages to a rotary vise. You just have to learn them and use them. The only disadvantage to a rotary vise I see is the higher cost. I also suggest that you first use a vise you intend to buy. The vise has to be comfortable to you so when you are using it your hands can move around without everything in the way. Of course what hook sizes you use etc. should also come into play when deciding what vise you want.
