Great question Pepe...and nice to see you back on BN!
Vanilla and Brown Sugar is amazing. I'm a fragrance snob, but I have to admit that I'd probably pick this in a blind sample, against other vanilla scents out there, that are 6 times the price. It also makes a great scent for bubble baths too (I'm a bubble bath freak!)
The Pink Grapefruit body lotion is pretty realistic too (it smells not just like the fruit itself, but like grapefruit peel...really tart and fresh). But since I have oily skin I rarely use this except as a hand lotion, where I find it has so much longevity that it inevitably clashes with whatever scent I'm wearing...so I tend to rarely use it.
Besides these 2, the others just seem kind of boring (yawn), to me.
