I actually got one of each to try and here's my review of each flavour:
1. Black Sesame: unlike any other protein bars or wafers I've had. Very unique and interesting taste. If you love sesame you'll love this!
2. Blueberry Cheesecake: also pretty unique and the blueberry smell/taste is really strong! Good for people who like more fruity flavors.
3. Chocolate: as a chocolate lover, this is my personal favorite! Because it's not super sweet, it does taste more like a dark choc (vs. milk choc) which I love.
4. Peanut Butter: very creamy and exactly what you'd expect. Can't go wrong with a good PB snack!
I like that all of these aren't super sweet and don't make me feel disgusted like some other protein bars lol.
