You can think of UVProject as a "baked" or "sticky" projection.
The main difference is how they'll behave if you transform/deform your geometry AFTER your projection. UVProject "bakes" the UV values into each vertex, so if you transform those vertices later on, they'll still pull the textures from the same coordinate. The other difference between UVProject and Project3D is how they behave when the aspect ratio of the camera window is different than the aspect ratio of the projected image. With UVProject, projection is defined by both the horizontal and vertical aperture. Project3D only takes the horizontal aperture, and preserves the aspect ratio of whatever image you're projecting. Hope that makes sense.
