Outside the amazing(ly unrealistic) Active Skill, he's pretty awful really. Stats are junk, coming in at only 453 weighted before plus eggs, two Awoken Skills are wasted to make him bindproof, a trait that only really matters to Leaders and bind-clearers, and his Leader Skill doesn't provide any form of tankiness that is necessary in today's endgame content. Oh, and his base form is likely of six-star rarity so, good luck actually pulling him if you're light/non-IAP.
