Knoxville Gray vs Mountain Pass
Where Knoxville Gray belongs to Benjamin Moore's range, Mountain Pass is a Sherwin-Williams color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. They have nearly identical light reflectance values (16 vs 14), so they'll read as similarly Dark in most lighting conditions. Knoxville Gray runs blue while Mountain Pass is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
