I love them both. The original is a barbershoppy, soapy scent with a hint of candy chewing gum cigarettes. Intense is remarkable in that it echoes the signature of the original but picks up a bit of what I like about the Prada Amber Pour Femme EDP with its heavy patchouli/labdanum base.
I didn't quite love Intense at first sniff, because I was unsure of its longevity-- but it's gone into heavy rotation and it's versatile enough for any season. On me, I actually find Intense to wear like a mini-Musc Ravageur. It's a bit cleaner and a touch fruitier, but has a lot of bergamot/oriental/vanilla absolute/musc and feels like a cousin to MR. I can see where some would be underwhelmed with Intense, especially those who haven't spent enough time testing it, but it's one of my favorite releases from the past two years.
