RE: which bow?
Price is going to be the main determinant for suggestions. You mentioned two of the flagship bows from two of the most popular companies right now. With that thought in mind price probably isn't an object. However, it would still be nice to know regardless.
I make no attempt to hide the fact that I have been a Bowtech fan for several years now. The Guardian is reported to be everything they are advertised as. Fast, accurate, quiet and with little recoil or vibration at the shot. Throw in the customer service that Bowtech is known for and I do not know how you could ask for more from a bow or bow company.
