Acrylic stucco may be a bit different than the normal form and thus has different characteristics and properties that accompany it like textures and finishes. Acrylic stucco is essentially like an exterior quality paint that has sand mixed into it. There are a good sort of different textures that you simply are able to do from using this particular material.
Really, there is no limit to how many different types of textures you can achieve using a synthetic or acrylic stucco. You can basically achieve 90% of the same finishes that you could with traditional type stucco, but it will have a few minor differences that you need to take into consideration.
