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.
Well, your opinion is correct. The issue of transaction fees has affected ETH, but it is still a reputable and good coin today. It's second only to bitcoin, although BCS is very well developed, I don't think it would be a better option than Ethereum.
Ethereum is still chosen by many people to invest anyway. I'm one of them, too.
