Dynamic batching or Baking meshes into tiles ?

Hi there

I am working on a kind of endless runner game. So i need to generate tiles and spawn them in runtime. My models are in moduler design so they are tiny parts,because of that I could use dynamic batching and get only 1 or couple of more draw calls depending on situation. But i am afraid of getting cpu or gpu overhead from hundreds of saved batches. So there is another method i could use. Predesign tiles and bake them into one meshes each. And get 10 or couple of more drawcalls from them.Which one is cheaper ?
Thanks
