Hello Mike
I have never used the Kirkland, but I feel safe in saying that I know that I have never smelled the likes of this in any detergent.
It is the most powerful I've come across!
After receiving them, I had the same reaction as Laundress did, and was not able to stand to have them in my laundry room. Every time I walked in, the scent was... well like she said, a "strong mens cologne" after half a day I couldn't take it anymore, so I put each box into a ziplock bag to reduce the scent level in the room, and thats where they stayed until they left me, and landed with her.
I know this sounds as though it's someone being overly sensitive, but really Mike, they are that strong!
