Helldivers 2 or DRG?

both games pretty much are very similar in terms of objectives, kill bugs/aliens, explore, both have friendly fire, player customisation, but i was just wondering which one is better? and i mean better in terms of more content, uniqueness, fun, chaotic, replayability, let me know what you guys think me and my buddies are dying to find a new co op game to grind all night.
