Surrati Oudy Woody is a piercing, high-pitched, searing, and musty woods. I apply this one lower on the torso, under clothes and often as a base for layering. I could see this one really grating on the wearer (and others) if too much is applied or it being applied too close to the nose.
Al Rehab Oudy oil has a deeper, earthy sweetness, relatively speaking; the spray, more peppery. I apply this on open skin and don't worry about getting it too close to the nose if you know what I mean.
