Flowery flavors, like lavender or rose.
Yes I am out there eating essential oils. (Not really)

Aside from those, since they are not very common and only some bougie-ass icecream shops have such options, I am more partial to things along the lines of chocolate/coffee/vanilla/cinnamon/cookiesncream/etc., most flavors that aren't fruity pretty much. But if an ice cream shop has limited edition flavors for a holiday or event, then I am extremely likely to try those out.

Regarding brand, I have no brand preference.
