I've always enjoyed having a bow quiver if I'm hunting something that I'm trying to ambush. The obvious one is deer, but even if I am trying to be somewhat mobile with turkey, I still stop and set up some sort of ambush. I like to be able to take the quiver off once I'm set up. It makes my other gear easier to carry.
However, if I'm just going out to roam for squirrels, rabbits, etc., I enjoy having my arrows in my cat quiver mini.
Obviously it's a preference thing, but the discussion and new ideas are half the fun.
