Which Crypto-Currency is Best?

I have gone through many Crypto-Currencies like Bitcoin, Litecoin, Peercoin, Ripple, Dogecoin etc.

I wish to know which of them is best?

Ex: If i go for Market Capitalisation; Bitcoin is best, if i go for Supply; Dogecoin is best, if i go for price there are many cheaper options available etc.
