These should be the same thing, or close enough to. Both involve the enemy making a perception check against your stealth, which they would have Disadvantage on if Hexed. And if enemies are using their passive perception (10+perception bonus) against your rolled stealth, then Disadvantage should give them a -5 to that value.
