It's all about the Erolfa. (I still have no idea what a beach smells like, and what with the anosmia thing, WON'T know, but... to put it simply; Erolfa good.)
Sampled VIW, and it was nice but I'm not big on smelling like a coconut.
SMW... not sure, it didn't make an impact on me when I smelled it at the store. I received a sample, but it doesn't help me now. (I've heard it smells similar to Himalaya, which in turn is similar to PR's XS, which I like... for whatever that twice-removed is good for.)
Imperial I kind of like, my girlfriend -loves- it.
