Both make good bows. I honestly can't say I'd prefer one company's products over the other. My choice would definitely depend on the individual bow models I was looking at.
I would suggest adding Bowtech or Diamond to you list though.
Even though I shoot a Mathews, I agree with Arthur 100%. If you can afford Mathews, you owe it to yourself to try the other top of the line bows. Everyone has a different idea of what's best, and while I love my Drenalin, some don't like it. The "BEST" bow is, without question, the one thatYOU like the best. It's that simple, and it doesn't matter what anyone else's opinion is.
