I can see a decent argument that the Korean ceasefire is qualitatively different; it arose less from an attempt to stop fighting, and more from a conflict where no one wanted to keep fighting but peace terms couldn't be settled. It wasn't envisioned like ceasefires in Syria, Palestine, or Ireland, as a way to stop killings while peace talks happen. Having said that, it certainly deserves mention as an exceptional result. Many of the border incidents have been larger than the events that broke other ceasefires, but the fundamental peace has held.
