I would probably smack the tard. I'm usually not a fan of those cactus bucks, but he branches out pretty good and has some cool mass. The other one is just your average 3x4 management buck. Nice buck, but I like the "wow" factor of the tard.
Depends on where you're hunting. Probably neither. Not into the cactus bucks myself, although I would take one if he was quite a bit bigger than this one. The other buck is a non-shooter anywhere. JMO.
