You could also add smart contracts to the list of "features".

About an "ultimate blockchain".. I don't know. Humans do like variation. Some don't care that Bitcoin is only pseudo-anonymous (and making it truly anonymous may give reasons for banning it). Some care only about smart contracts, others not at all. And (unfortunately) the huge majority only cares of which one of these gives better investment returns.

Crypto is not as mature as we'd like to believe. Maybe the time for "ultimate blockchain(s)" will come in the future. Until them, let them compete and prove their value (and fix their weaknesses).
