Ra is way better then obelisk right?

you see alot of people tell me that ra sux cuz it can be destroyed but obelisk is destroyed at the end of the turn YOU CANT WIN WITH HIM no mater what with ra there is a chance to kill your opponent in the first turn use giant trunede er whatever and use penguin soldeir (before ra is summoned) to bring ur opponents monsters to his hand then all u have to do is activate secret barrel and u WIN!
