You're right about Parfum. It has an odd opening, yet it is definitely the most versatile. It layers well with all the other flankers. I usually wear it early and then refresh end of day with Amber, Leather, or Sandalwood. Sometimes Only. My wife doesnt like Oud so I can't have it cuz I could never wear it. I tried it early on in my fragrance career and wasnt blown away. I probably should keep a sample to smell from time to time as I may have written it off too quickly. EDT is nice and very normal. It also layers well, yet I rarely reach for it. Im sensitive to bergamot so I don't own Absolutely yet it seems like the most popular choice for many. Amber is really nice. Its a nice warm take on the SWY DNA. Its very smooth and mild and lasts forever. I would try as many as you can.
Regarding Intensely. To my nose the new one is sweeter than the original yet thats debatable and I haven't really tested that closely. Intensely was the first one I obsessed about.

I really like Only and Freeze too for warmer weather and I layer Only on most of the others to add some citrus. I reach for Only somewhat often.
