For me, Ethereum doesn't really need to prove itself as the best coin than other coins. Why I said above that this is the time for ETH to prove itself, because so many people compare ETH with other Altcoins.
I think it's clear.
In the past ETH has proven itself to be the best among other Altcoins and now there is no need to do that anymore, because simply by making good developments it will become even stronger over time.
New altcoins have been arising in the market but none of them has beaten the performance of etherem. So definitely, there is no need to compare ethereum with those other altcoins because it will always ethereum who will excel.
And with the current London hard fork, etherem has given more momentum to move in an upward trend. And hopefully, once this fork has become successful, the issue of ethereum about its gas fees will now be resolved.
