It's easier to answer the other way around. I don't like any of FA's (or anyone else's) floral flavors.
I don't like the pipe tobacco or cigar flavors, rarely vape any tobaccos other than light cig flavors like 7 Leaves, Maxx Blend, occasional Virginia, or RY4. I'm no fan of Oba-Oba, because I can't figure out what it's supposed to be. On the fence with Hypnotic Mist, which is almost as puzzling to me.
FA's Cappuccino is not great (but Coffee Espresso, Fresh Cream make an awesome one, so no problem).
I'm liking Flavor Apprentice's Banana and Pineapple better than FlavorArt's, because they're stronger.
edit: one more - I could do without Bread Crust because just a drop would last a lifetime
The other 75 or so FA flavorings that I've got, I think everyone needs to have.

I need a few more, too.
