My experience is much different from yours, as I find Amber Oud and Incense Oud anything but skin scents. I guess when I bought them it had not been reformulated, and you may have been trying post-reformulated stuff.
Personally, I really like all of them (except Gold Oud or Black Oud - never tried those)
My favorites are (in order):
I think all 5 of those are excellent and worth a look for sure. But if everything from this house has recently been watered down, then maybe all bets are off.
