Like everyone else, I would shoot the buck on the left because of his mass and width and character.
The buck on the right sure has some big forks though and as we might be finding out soon scores really well!
I don't think you are wrong for shooting a lower scoring deer if it looks bigger...B&C is totally weighted towards tine length and most of the time a buck with 45" of mass and shorter tines will look bigger than a buck with 35" of mass and big deep forks.
The heavier buck only gets 10" of extra credit for his mass, but if the deeper fork buck has the same size main beams and inside spread, but 2" of extra length on the G2, G3 and G4, it ends up bigger by 2". Just comparing pictures of the two, most would say shoot the heavier buck because he looks way bigger. If he has 4" of extra length on each of the 3 tines on both sides then he ends up scoring 14" more than the heavier buck, could be the difference between a Boone and Crockett buck and big heavy bad boy non-B&C buck.
