If Bitcoin is king of cryprocurrency, then Ethereum is the king of all ICOs ,do you agree? Stella,neo and no other blockchain has hosted ICO than Ethereum.
I don't agree with your opinion.
and for the designation I think bitcoin is the most appropriate.
and for ether it's better as the queen of all existing altcoins.
I think that's right for both.

the more ICOs who use Ethereum, it will make Ethereum the king who controls the ICO in the future. currently there are many ICOs that use Ethereum as an allocation. so that many interested people have more Ethereum. thus making Ethereum so valuable.
