models

I am using XNA 4.0 and I wonder if drawing models with multiple meshes is better by filling the vertex and index buffers first and calling GraphicsDevice.DrawIndexedPrimitives() or by simply using good ol' foreach(...) {ModelMesh.Draw()}.

Is it possible to add data to vertex/index buffers at all in order to pack all the models on the scene in them and then call Draw only once per frame?

I would appreciate a link to an in-depth explanation. Thanks.
