Both would be big enough to get me excited, so honestly, I'd target the one that gave me the best shot opportunity. If the opportunity was the same, I'd obviously target the bigger / older buck
Depends on your definition of immediate area. If it means I just think or know an older / bigger buck is in the area, but not in sight, I would not hesitate targeting the younger buck pictures above.
All property I hunt has competing hunters on and around it. I don't have the luxury to pursue specific bucks for multiple seasons or even a single season. When opportunity knocks, if I don't answer the door, that's often my only opportunity for that or multiple seasons.
I don't run cameras and don't age deer on the hoof, outside of recognizing a mature buck vs a young buck, but I've only harvested a couple large racked, what I believed to be young bucks. I didn't lose any sleep over them because dead is dead and in the end, I'm a hunter, and I accomplished what I went out to do.
