The good thing about this decision is that there is NO wrong answer. Both bows are much, much, much more than adequate.

Also, the discussion about one bow being faster than the other is fun to talk about, but has no bearing on which bow is better. Both bows have speed that is MORE than needed to kill any game on this continent. Dead is dead. I would bet that arrow drop between the two is pretty negilable too.

If you have the opportunity to shoot both bows, then by all means do so and pick the one that feels the best to you. As for me personally, I have shot only the switchback, and it was awesome to me, so I am getting one and I don't really care what the other bow feels like. I will be happy with the switchback. Had I shot the Alliance first and liked it, the same could be said about it.

Good luck. Might need to flip a coin?
