I will second the INW Shisha Strawberry, if I could only keep one it would be it. I do still use TFA Ripe and regular Strawberry as well as CAP S SB and FA SB in mixes that I made before getting Shisha. The INW mixes well with CAP but you need to let it steep a little more because of the chemical smell the CAP can have when fresh. INW regular SB is pretty good as well, more of a natural SB, the Shisha version is like that but with a sweet glaze poured on top, sort of like what you would get on a SB Shortcake.
FW and LA SB's are a skip for sure. I just picked up Delosi SB which is more of a prominent SB like the Shisha but different, only tried it in one mix so far and it is good but not Shisha. I also got a couple of samples of One on One SB Ripe and SB Cotton Candy, there both decent, I like the cotton candy version a little better. Neither is a Shisha beater but I can definitely use them in some mixes.
As far as the question above me about the closest to a candy type flavor.....hmmmmm, tough question. If you consider strawberries in a sweet glaze to be like candy then it would be Shisha. It is also one of the most prominent SB's flavors, it doesn't tend to get lost in a mix like other SB's can. TFA's regular SB is more candy like than the ripe version as well.
Everyone's taste is different but there seems to be a large fan base for Shisha SB, myself included.
