Bitcoin maximalists believe that there is no other block chain solution that will solve the world's problems because it has the best network the most value and the best design and programming.
Later study showed that Satoshi's Code were functional but not well optimised and he used more code than necessary.
Bitcoin is believe to be the best because it's the closest thing we have to decentralization (well and also it's security)
Although Bitcoin's blockchain network has increased its capability by offering smart contracts, it lags behind Ethereum and others in decentralized financial applications.
Simplicity is strength. Always note that there's always a trade off.
Bitcoin is money and I prefer it being simple.
