Ocean Floor vs Powell Gray

Both from Benjamin Moore's palette. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (14 vs 15), so they'll read as similarly Dark in most lighting conditions. Both lean blue, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
