Oddly enough not many. Tombstone comes to mind. I will have to look. High Plains Drifter I have somewhere.
As far as television series are concerned, four: Have Gun, Will Travel Wanted Dead or Alive The Rebel The Loner No films.
Unforgiven (Clint Eastwood) Fistful of Dollars For a Few Dollars More The Good, the Bad, and the Ugly Hang 'Em High El Dorado Chisum Young Guns Outlaw Josey Wales (VHS, but no longer have a VCR)
Only a few: Wind River (2017). The Quick And The Dead (1995). 3:10 To Yuma (2007). The Revenant (2015).
Have Gun Will Travel, the entire 7 season series Bat Masterson (all episodes) Lawman (complete series)
I'm guessing around 20 or so. Little Big man Pat Garret & Billy the Kid jeremiah Johnson Once Upo a Time in the West High Plains Drifter unforgiven Ravenous (Horror) Man in the Wilderness A Man Called Horse Chatos Land The Wild Bunch McCabe n Mrs. Miller The Train Robbers Tombstone Wild Bill The Long Riders The Deadly Trackers Django Kill Lonesome Dove More I can't think of.
About 50 feature films, mostly on BD. Some TV shows on DVD: Gunsmoke (incomplete), The Rifleman (incomplete), The Westerner.
Can’t think of? Had to dig mine out, they started to pile up. Aside ..you’ve got a lot of 10/10s in your list.
Gosh! Good question.... The answer is I have no idea. Probably 20 or 30 or so? My favorite Westerns are the oldie's. 1950's - 70's era.
To many to think of, I will have to do a count when I get home. One of my favorite genres besides film noir.
I can't get into modern Westerns so much, and yet I've tried.... 'Deadwood' for example. No Thanks, Gimme John Wayne any day of the week.
