I guess it all depends on what he is wanting to spend and which model of each he is looking at. Is he looking at single cam or dual cam? What two models is he comparing? It all really depends. I owned a PSE for a year and then bought a Bowtech(who ownsDiamond) My Bowtech completely blows my PSE out of the water, but it is also because I bought the best Bowtech had to offer. I am sure I would be happy if I had bought the best PSE had to offer. He really needs to shoot each one and buy the one that feels best and that he is most comfortable with.
