I am also a fan of ETH. I think ETH is a pretty good coin for future investment. It's just that the drawback is a large fee as you say. I think ETH will be more advanced for the next few years. And also a lot of coins that use the ETH network.
For the problem of transaction fees on the Ethereum network, I don't see it as a drawback because with the current price of ETH, I think the amount of transaction fees that must be incurred is still very commensurate and worth it even though some people say it's not affordable , even though in the past the expenditure of transaction fees was almost the same as now if we look at the form of ETH, only because the price of ETH in the past was still very cheap, so the costs we incur look very cheap, even though the amount of expenditure is also almost the same as now although in terms of dollars it has seen an increase due to the influence of the price of ETH itself.
