A few Reasons Ripple ISN't Bitcoin. Open to your counter arguments,

Ripple Network Effect - Small & Weak , No one has Ripple wallets.
Decentralisation - None. Large ownership of coins are with the founders.
Censorship Resistance- Low to None . Government or Banks (as Proxy for Government are able to censor, stop, amend supply or do anything they wish to Ripple. It cannot be an independent store of value.
Replication: How is ripple not simply replicated/ duplicated by the banks or government agency working with the banks?
More to come on this, just curious on your responses to points 1-4
