Some people miss interpret what Hiro was trying to convey. Yes you have the zodiac keys which is rare and gold but you also have keys like the Celestial spirit king. Also the gold keys were stated to be powerful but it was never stated the be the strongest of all the keys. You probably have different material keys and the material might not always represent the strength but the rarity of the key. As I look at it Silver keys are like tools, Gold keys are like mages, and rarer keys are like S class/Wizard saint/Guild master level keys. It is good to have a little of each but the rarer the key the more magical power it cost. Being a summoner gold/rarer keys are more useful since the actually fight for you while a silver key is a tool you have to use on your own.
