Looking for under-the-radar good Westerns.

Give me some underappreciated Western movies please.

I'm looking for ones that are rarely or never on "must-watch" or "Best Westerns of all time" but you think are tremendous.

I don't want to use the word "underrated" because that to me implies it wasn't as well-reviewed as you thought it deserved, which is not necessarily what I'm looking for.

My own suggestions in this vein are Meek's Cutoff and Bone Tomahawk, which are both contemporary but films of any age are absolutely OK. Thanks in advance!
