There is no second best to Bitcoin. There are two main reasons for this:
1. Bitcoin has a massive network effect and origin that cannot be repeated
2. Bitcoin can copy every utility with sidechains
Monero is a shitcoin. Ring signatures on Bitcoin is not a shitcoin.
Unfortunately, there is a massive campaign trying to stop true sidechains from being merged into Bitcoin. So definitely not the "first draft", but Bitcoin will eventually consume all shitcoins and fiat currencies to be the one money.
