It approachs absurdity and profound dissrespect to apply labels/perjoratives about playing styles in our little game to men who did this for real.
Everybody shot from dead behind with no warning whenever possible, and you will find that probably 80% of kills were scored this way. On the other hand, Richtoffen and Hartman had some white-knuckle dogfights themselves and there is little doubt they were skilled manuevering pilots. Voss's exploits and similar are just what you would expect from a cornered tiger facing long odds. Mainly, some pilots were luckier than others...some scored and scored without being killed or wounded, some died, some came close enough to feel the Reaper breathing down their neck but pulled it out at the last instant.
Honestly, the primary factor before in the making of an ace before all the radar, missles, electronics, etc, was probably eyesight, spotting the enemy first being primary. Then gunnery. Ability to withstand Gs in a high-speed turn, probably distant third.
