Here we go.
Hunter 1- tags out every year with average to mature bucks.
Hunter 2 - kills 6 does every year only
I'd say you may have a bit of bias with that "only" there on the 6 does. I would also say if a hunter is capable of tagging 6 does a year and not also connecting with whatever an "average to mature buck" is the deer herd is severely out of whack.
I've met guys who only want to shoot big bucks. I've met guys who like to shoot lots of deer. The first guy usually shot lots of deer and got over the bloodlust. The 2nd guy usually is quite capable of coming into contact with mature bucks, or at least is better than average.
It's hard to nail down a "good" hunter. A good hunter implies that there's a bad hunter, but how do we know one is good and the other is bad? When we rank people competing in sports we can do so because the playing field is as level as we can make it. There are too many variables in the country with regards to terrain, deer density, herd age structure, season duration and start/end dates, regulations, etc. And hunters themselves are unequal due to age, income, geographic location, occupation, marital status, and other factors that impact their ability to score.
If we go by antler mass, the Wisconsin boys have it in the bag. If we go by body count, the deep south probably comes out on top.
All that said, for me the tells that I'm talking to a good hunter are them demonstrating:
familiarity with the prey's habits and a knowledge of how they "fit" into the ecosystem
The ability to gauge the value of a particular piece of ground. Ie the odds of that piece of dirt producing the game theyre after
Familiarity with their hunting grounds.
A demonstrated level of awareness of how that hunting ground changes throughout the year, and how that change impacts their prey's habits
A willingness to lean into uncertainty and adjust when new info/patterns are emerging and adapt with the changes. Good critical thinking skills, but not prone to castle-in-the-air theories
GOOD "FINISHER" SKILLS. ie they can make kill shots, find game, get it out of the woods, and process it
Comfort and proficiency with their chosen gear
Notice these skills apply to everything from squirrels to ducks to turkeys to does to bucks.
