With flavours like matcha(level 1 to 3) to the usual few of houjicha and Earl grey and uncommon ones like iribancha, there are many options to choose from.
I had a double scoop of matcha 3 and Iribancha with the latter becoming my favourite now. The level 3 matcha was quite manageable in my opinion, you do get the intense flavour ending on a bitter note. Iribancha was the unique one, with a smoky flavour similar to that of a smoked ham turning it into more of a savoury softserve instead of a sweet one.
