Modifier wise, it is different(normal Cherry style vs Costar/iOne steel wire style)
Switch mounting wise, also different(5pins PCB mounted with aluminum plate vs typical steel mounted)
Keycaps wise, it also quite different(Corsair's one as below with significantly less curvy keytop while older BWU series using a tall DCS profile keycaps with quite curvy surface with a thin and fragile "X" stem, newer iOne make board having durandale tyle of "+" stem), you also notice that Corsair is putting a "-" on their numpad "5" instead of normal "."
Layout wide, it is still different(1.5,1.0,1.25,6.5,1.25,1.0,1.0,1.5 vs iOne's known 1.5,1.0,1.5,6.0,1.5,1.0,1.0,1.5)
