Yup, it's so superior that it seems ludicrous that others are considered comparable. The taste of it isn't quite like sugar, but it's close, and it's WAY better than any of the non-polyalcohol-sugar artificial sweeteners... and, IMO, is better tasting than isomalt, which comes second in tastiness to me, sorbitol 3rd place... I don't much like xylitol.

While it is technically a natural sugar alcohol, and can be refined from birch trees, most of the xylitol used in food products now is full synthetic or fermented with yeasts.

It is sweet. It is artificial (sometimes).

It may also draw additional water into your colon and have a "cool" mouth-feel, and it does add calories. Erythritol may be preferable for those reasons, even though it is less sweet. A common non-sugar sweetener mix is erythritol and stevia, which can, when proportioned correctly, add the same sweetness as an equal mass of refined sucrose.

It's also a laxative, so be careful how much you consume.
