Neither — Step1X-3D and TRELLIS (Microsoft) are both free, so the choice comes down to capability rather than cost. Both entries list what they uniquely do above.
Choose Step1X-3D if you need apache-2.0 two-stage geometry plus texture generator (1.3B and 3.5B models) for textured 3D assets; choose TRELLIS (Microsoft) if you need open-weight model outputting radiance fields, 3D Gaussians AND meshes from one representation.
