Re: best of...
Every other shisha out there has a strawberry and watermelon. You should get 50g packs of each and compare. AF has them, Pharaohs as 40g packs, Nakhla has 50g packs (grape, strawberry but I'm not sure about a watermelon by Nakhle)
Those brands are more "natural" flavors. The others are candy flavor and don't come in 50g, ie: SB, Tonic, etc.
I prefer the natural ones more.
