I've heard numerous times why that version is bad or wrong, yet it remains his most beloved and enduring version by a long mile.
I read the Denny O'Neill version and wasn't horribly enthused with his character or the story. He seemed like something straight out of a blaxploitation flick, and Hal was being set up as an unfortunate straw man over and over in that comic run. I got the feeling that Hal was supposed to (predictably) learn a lesson, yet John--who was angry and aggressive and called Hal a "whitey"--was just getting a pass for everything. It's worth noting that John only appeared like that in literally one comic in his history. It's not uncommon for characters to change quite a bit from their original versions before they get refined into what eventually catches on. For example, I'm sure we all know that Superman used to jump around instead of fly, and Green Goblin flew on a jet broomstick before his glider took hold.
The angry black man John never really took hold. The mentally ill philosopher John never really took hold. The marine John did. People often try different things until something works well. I believe the issues the marine John have faced were due to disinterested writers and editors, especially after seeing how liked he was on a show where the showrunners liked him and put effort into him. Though, obviously, it's perfectly fine for people to prefer other takes on the character.
If you comb through his history then all of that is explained. He joined the marines to pay for college tuition (Secret Origins #9) and he does speak up against authority when he feels it's necessary, like when he opposed a commanding officer in the Marines (Green Lantern Corps 2011 #25), which is why he left the marines.
