The verdict
On paper these two are close, 235 kg against 220 kg and 2550 mm against 2701 mm of reach, near enough that the spec sheet alone will not decide it. They run different controllers, the ABB IRB 6640 on the IRC5 and the Comau NJ-220 on the C5G, so whichever platform your team already programs and stocks parts for is a real tiebreaker. For a tight or overhead cell, the Comau NJ-220 lists Ceiling mounting, which the other does not.
