It is quite unusual for two Custom minifigure designers to release the exact same minifigure, and left a lot of people undecided as to which one to buy. So hopefully this video should clear things up for you.
They are the Captain Stealth Suit custom minifigure by Minifigs4u (on the left) and The Captain custom minifigure by eclipseGrafx (on the right).
So which do you prefer?
