From Young Guns
Billy the Kid interrupts Dick Brewer’s dinner prayer …
Billy - “Jeeze Dick it’s gettin’ cold”
Brewer draws his guns… Billy pulls his faster.
Billy - “I coulda killed ya Dick. I coulda killed ya. But I don’t wanna kill ya… I wanna eat.”

From The Revenant:
Boone: I’m actually starting to miss my wife’s cooking.
Stubby Bill: Shit, I’m actually startin’ to miss your wife.
You think Pike and old Sykes haven’t been watchin’ us. They know what this is all about - and what do I have? Nothin’ but you egg-suckin’, chicken stealing gutter trash with not even sixty rounds between you. We’re after men - and I wish to God I was with them. The next time you make a mistake, I’m going to ride off and let you die.

Should we escort out people who post one already mentioned in the thread? 
Grimes: Mister, you’ve got alot of hard bark on you walkin’ down here like this. Now, I owe you. You put two holes in me.
John Russell: Usually enough for most of 'em.
Grimes: Don’t try it again, that Vaquero is more than a fair hand.
Grimes: You got the money?
John Russell: Guess I brought my dirty laundry down by mistake.
Grimes: Let me see it.
John Russell: Look for yourself.
Grimes: [opens bag, pulls out a handful of clothes] Well now, what’ya suppose hell’s gonna look like?
John Russell: We all die, just a question of when.

You wanna know what your boy did? I pulled my BIG, BLACK, PECKER outta my pants. And I made him crawl in the snow on all fours over to it. Then I grabbed a handful of that black hair at the back of his head … and I stuck my Big Black Johnson right down his goddamn throat! And it was fulla’ blood … so it was warm. Oh, you bet your sweet ass it was warm. And Charles Chester Smithers sucked on that warm black dingus for as looong as he could. Hahahaahaha! Startin’ to see pictures, ain’t ya?
Yeah, Warren, that’s the problem with old men. You can kick 'em down the stairs and say it’s an accident, but you can’t just shoot 'em.
The little bastard shot me in the ass!
Feathers [Angie Dickinson]: This isn’t the first time that handbill has come up. I’d like to know what to do about it.
John T. Chance[John Wayne]: Well, you could quit playing cards… wearing feathers.
Feathers: No, sheriff. No, I’m not going to do that. You see… that’s what I’d do if I were the kind of girl that you think I am.
Feathers: I thought you were never going to say it.
John T. Chance: Say what?
Feathers: That you love me.
John T. Chance: I said I’d arrest you.
Feathers: It means the same thing, you know that.

I think I would have to challenge your premise. My favorite movies fall into a variety of categories and if truth be told my favorite westerns are comedies.
The AFI list was created in 1998 but my guess is that you are not arguing that there have been a large number of the best ever created since then. Highest on the list at number 33 was High Noon and only 6 others made the top 100.
Texas isn’t even a state. How big can it be?!?
One of my favorites:
John Cleese: “Today, my jurisdiction ends here!”
Well, *Quigley Down Under *isn’t what I would call a “traditional Western” but the period is right, even if is set in Australia. And Tom Selleck, playing Quigley, was SO hot.
Major Ashley-Pitt: In our experience, Americans are uncouth misfits who should be run out of their own barbaric country.
Matthew Quigley: Well, Lieutenant…
Major Ashley-Pitt: Major.
Matthew Quigley: Major. We already run the misfits outta our country. (spits out a gout of chewing tobacco) We sent 'em back to England.
I reckon so.
