Initially I hated Prada Amber PH. When I tested it at Nordstrom, I thought it smelled feminine and not just girly, but in a "Friends of Dorothy" way. I suspected campiness. I couldn't help it-- that's the first thing that came to my mind. It also smelled like a freshly washed poodle.
Oddly, I kept dipping into my sample and I started to do a 180 on the Prada. What I like about it is that on one hand it has a very smooth seamless feel-- yet it becomes easy to pick out each one of its advertised ingredients. When you've worn it a few times, and I mean FULL wearings of a whole day, you begin to appreciate its luxurious barber soap quality. I had a Macy's gift card and I went and bought the big bottle with the fancy prestige atomizer. It's something I wear often to work. It'll never be the most masculine scent in modern terms, but it's very individualistic, smooth and attractive.
CdG 2 EDP is a nice fragrance, but it's one I don't wear much-- I think it's just a little too "perfumey" for me with the aldehydes. I'd love it on a woman. I do know what you mean about the comparisons to M7-- they both have a certain exotic wood/spiciness.
