Of course, as with any category, it depends on the fragrance - I love the tuberose in Carnal Flower; hate the cold, anemic faux-tuberose note in Vierges Et Toreros. In general, though, I have a great fondness for tuberose.
I love gardenia, but I've very rarely smelled it well-done. Kai was a disaster on me - totally unlike the real thing, or any flower that grows outside of air-fresheners. Michael Storer's Stephanie did a decent job, but it was still off and a bit watery and distorted. It's beautiful, but the difference between it and the real thing is still as wide as that between Les Demoiselles d'Avignon and real women.
Jasmine can be nice, and I love the natural absolute, but I don't have enough experience of it fragrances to say. Too often I've smelled "fruity-floral" jasmine, which doesn't jive with me.
If muguet is a white floral, then yes, I like it. Same goes for orange blossom, if it smells natural, which could also be said for lilac. There are some floral notes I don't have enough experience with to say - narcissus, hyacinth etc.
I especially like white florals in orientals. Ayala Moriel combines two of my favorite notes - tuberose and myrrh - in her Razala, and the effect is both beautiful and unorthodox.
