I agree with Rob, that it is all up to the individual. I don't know that there is one perfect solution. My favorite is probably my Eagle's Flight four arrow bow quiver. It is so light, it has little effect on the feel of the bow. The new ones have an improved attachment system that I think I'll order.
I have a Thunderhorn Linx that is a fine quiver. It works well on my recurves, but it's just a tad heavy for my lightweight Kanatis. It just seems to throw off the balance on them. The plus side is the bar between the hood and arrow clip keeps the halves from sliding apart.
I haven't tried a back quiver. The thought of jabbing razor sharp broadheads down my back gives me the willies! I have a side quiver from Raptor Archery. It works okay, but the area I hunt is full of buck brush, gooseberries, and multiflora rose bushes, things that grab onto whatever you carry. With a bow quiver, I can just hold my bow overhead. With the side quiver I was constantly fighting to drag it through the brambles.
If you can try several, that would be a good plan.
