I believe that ETH will reclaim it's glory back once gas fee issue is solved, there is also a big difference between BSC and ETH that will still make many prefers ETH, that's the fact that BSC is Centralized and ETH isn't.
Of course, ETH is better than BSC since it appeared earlier, it is a decentralized cryptocurrency, and also has a development ecosystem and a large community. BSC is a new cryptocurrency from Binance that was probably launched to temporarily and partially replace ETH. These are all from ETH's problems related to the price of commissions. I also believe that ETH will be able to solve its problems and ultimately gain even more recognition and success.
