We could even say that "the market has decided" that PoW is superior because Bitcoin is still #1 by a wide margin, after 12 years of PoW/PoS debate. The small amount of successful PoW altcoins is not contradicting this, because PoW tends very much to a single "winner" due to the 51% attack threat for smaller blockchains. So it's reasonable for altcoins to adopt PoS because it provides reasonable security, as a tradeoff to less decentralization and the "weak subjectivity" problem.
Well, here you are actually contradicting your earlier point somewhat, aren't you, namely that PoS and PoW (and in particular Ethereum and Bitcoin) are
not in direct competition?
I agree with this latter statement that Bitcoin currently occupies the "winner" spot. But this also means that Ethereum could in theory become the "winner" at some point in the future if Bitcoin crashes (on its own or by force), and that the price of ETH would likely increase as part of this happening.
