vsThis is the one comparison in the set where the right answer has nothing to do with quality. Zoo generates parametric B-Rep CAD and exports STEP; Sculpty generates polygon meshes. Those are different kinds of object, and your project only accepts one of them.
If the model is going to a machinist, a CNC quote or any engineering process with tolerances, Zoo is the only one of these two that helps — a mesh cannot carry dimensions, and no amount of generation quality fixes that. Zoo is also open source with a real geometric kernel behind it. If the model is going to a game engine, a website, a film, or a 3D printer, Sculpty is the answer: meshes are what those pipelines consume, and Sculpty converts to STL for free and can order the print. Worth knowing before you commit: independent testing found Zoo accurate on simple parts and unreliable as complexity rises.

Does anyone downstream need to change a dimension? If yes, you need CAD, and that means Zoo or a traditional package — a mesh is a frozen surface and editing it to a tolerance is misery. If no, you need a mesh, and a generator will get you something far more interesting than a CAD prompt ever will. Decorative object, character, prop, product visual: mesh. Bracket, enclosure, mounting plate: CAD.
Yes — it exports STL alongside STEP. But if printing is the only goal and the part is not engineered to tolerances, generating a mesh in Sculpty is usually faster and produces more interesting results.
No. Sculpty produces meshes — GLB, STL, OBJ, PLY, glTF, plus FBX, USDZ and 3MF on Meshy generations. For parametric CAD you need a CAD tool.
