Mass and extra tines on #2 has my vote. #1 has fairly short main beams and inside spread. #1 is a fantastic buck but there aren't many around like #2. #2 has the potential to be a real jaw-dropper in a couple years.
#2 is awesome but the flair of the g3's on #1 is also awesome. I would take which ever one provided the first clean shot opportunity. I don't see how you could be disappointed with either on the ground and then your wall.
I would be happy with either. If I didn't have much time to decide, and they were side by side, I would take #2. However, if it was an area I hunted every year, I would take #1 and hope #2 survived another year or two because he has potential to add significant antler in future years. He may not, but I'm fairly confident that #1 will never grow significantly larger antlers.
If it was an area that I may not get to hunt every year, I would go after the buck that I thought I had the best chance of killing when the season opened.
