Still believe Ethereum is here to stay and with immutable it has almost no gas fees the only gas fees are sending and withdrawing your Ethereum from Immutable.
By far it is ETH, not that it is the "best" but that is what everyone else uses and to be fair all the good games and nft stuff are there. This doesn't make ETH the best, it makes it preferred but as long as it is prefered then I do not know what to tell you. Would all those projects going to Solana make solana better? Yes, if they moved to ADA would they make it the best? Yes.
So, what makes ETH the best network is not that it is the best itself, but all the projects under its command. Which is why I believe that we should not be really shocked when people say that they rather invest into something in the ETH world because everything else is there as well.
