It really is just a matter of preference. I used to hunt WMAs and any buck you got was a good one. In the past few years I've been hunting on a friend's farm and he told me I could kill anything I want but they hold off on young bucks and so do I. The place is over run with does and this year I passed up 2 small bucks and took 2 mature does. Had I been hunting on a state owned WMA, I might have pulled the trigger on one of them.
