The preminary function of  a capacitor as studied in elctrostatics is storing charge. So, under the realm of electrostats, a capacitor with high charge storing capacity is better.

but when alternating current is concerned, the situation is different.

A GOOD CAPACITOR HAS THE ABILITY TO STORE THE MAXIMUM AMOUNT OF CHARGE WITHOUT ANY LOSS WITH TIME.

WE KNOW THAT Q=CV , SO C=Q/V . So if the charge stored is more and the voltage applied across the capacitor we have taken is lesser, the capacitance will be more,.
