For example, compare two locations, one at sea level, one at 6000', both at 80 degrees and 25% relative humidity. Will a person feel any difference? Stated another way, is 15% just as dry feeling and 70% just as sticky feeling regardless of elevation/air pressure?

Lower pressure means lower effective humidity. The ratio of water to air is the same, but with more pressure, there are more water molecules to bounce against your skin.

Sweat also evaporates faster at altitude.
