Verdict

Situational
Mega Starmie is a solid but not elite Water-type attacker, sitting at Tier B (#20) in raid performance. With a max CP of 4,184 and base stats of 276/229/155, it can fill a role on your team if you lack stronger Water-type counters. The best moveset is Water Gun paired with Hydro Pump. Consider investing if you need a Water-type attacker now, but hold off on XL Candy investment as better alternatives exist. A useful stepping stone rather than an endgame pick.
