While I like and respect Monero, in my opinion Pirate Chain is better than Monero because of 3 primary comparison points.
Pirate Chain has an Anonymity Set of 887,488 currently (as per https://explorer.pirate.black/stats), which grows with every transaction, vs. Monero's fixed 11 mixer. So with actual anonymity, nobody comes close to Pirate Chain.
The above stated Stock to Flow ratio of Pirate Chain is about to at least equal, if not surpass, Gold; and in the following Halvings will leave Gold in the dust of value. The more I reflect on this, the more excited I get about Pirate Chain. Whereas, I'd have to do the math for Monero, but given after it reached it's max supply, they decided to continue on with 157,860 per year, I don't believe it comes close to Pirate Chain's Stock-to-Flow Ratio.
Pirate Chain has a very unique 51% Attack Protection system, which notarizes redundant copies on the Komodo blockchain and the Litecoin blockchain. Thus, to do a 51% attack one would have to attack ARRR, KMD and LTC simultaneously.
