We report on frequency comparison of two optical lattice clocks based on fermionic 87Sr trapped in 1D optical lattice and bosonic 88Sr in 3D one. We discuss that these two lattice clock configurations would optimize the lattice clocks' performance from the view point of the quantum statistical properties of interrogated atoms and optical lattice geometries. The frequency comparison of two optical clocks offers an important step to investigate the lattice clocks' uncertainty less than 10-15, where no working standard exists.
