Bitcoin should not be compared with any other crypto coins that are introduced later after the success of Bitcoin. Bitcoin is one of its kind and unique in that no other asset can even replicate the advantages, the decentralization, and the privacy it provides. It's literally a balance of everything and the most important unique selling point (USP) of Bitcoin is it's Bitcoin Halving System. That's some great way to reduce the supply of Bitcoin in a calculated manner.
Well, you compared BTC yourself to other coins. It has many advantages, including decentralization and privacy. You easily can compare it to other coins and say that it's better.
Without comparison, how can we know bitcoin is really the best coin and it deserves to be king? Even if it is the first coin created, but if it does not outperform later coins it will not be considered king. But to know whether it is really good or not, we need to compare to know who is the real king.
For me, as long as altcoin projects are created with the intention of selling tokens for profit, and they are not focused on utility, privacy. There will be no altcoin worthy of comparison with bitcoin.
