Are you going to shoot BU( Bowhunter?) with fingers? Only reason I ask is these are short A2A bows for fingers.
Out of these three from the stats you've provided the Diamond looks like it might have the edge for speed and forgiveness, the cam can also be adjusted to give 65%-80%, so you could shoot a bit more poundage on the higher let off to keep the speed up. You're basically looking at a Bowtech on a budget with this one, so the engineering will be good
It'll probably come down to which feels most comfortable for you, so if you have the chance to shoot them back to back that would be your best bet.
