I am partial to Allulose [1] and Stevia [2]. A lot of people find their taste bad, but I've grown used to them, so much that I don't "taste" them anymore.

It's not terrible, I've used it in hot drinks (fruit green teas) to give some sweetness.

Doesn't immediately taste horrific like Stevia.... I'm glad the fashion for shoving that in everything has passed.
