The verdict

On paper these two are close, both carry 5 kg and 910 mm against 850 mm of reach, near enough that the spec sheet alone will not decide it. They run different controllers, the Mitsubishi MELFA ASSISTA on the CR800-05VD and the Universal Robots UR5e on the PolyScope, so whichever platform your team already programs and stocks parts for is a real tiebreaker. For a tight or overhead cell, the Mitsubishi MELFA ASSISTA lists Floor and Ceiling mounting while the Universal Robots UR5e lists Any mounting, which the other does not. Both are aimed at assembly and machine tending, with the Mitsubishi MELFA ASSISTA stretching to packaging and the Universal Robots UR5e to quality inspection.
