You talking about something that's already been fixed mate, Ethereum transaction fee is no longer a problem and August is close which we will see even better and cheaper transaction fee on Ethereum network, the headache is already over, as for the question you asked many people just prefer ETH and you and I can't change their minds
Well mate, how sure are you that Ethereum transaction fees are no longer a problem,?? Because I personally think it still lingers, just last week, the day shapeshift announced airdroping fox tokens to their long time users,, fortunately, I was one of the beneficiaries and we know, Fox is an erc20 token, I remember gas fees on Ethereum blockchain that day was hell, I spent almost half of the airdrops worth to in fees during claiming, and after successfully claiming the airdrop, I was really angry at the amount of money i spent on fees during the claiming process, and this made me to sell of the fox tokens so as to recover my money back which I borrowed from my other investments.
I personally think nothing is solved yet, the reason why it looks as if fees on Ethereum is low is because not many people use the blockchain anymore, the number of transactions that happens on Ethereum blockchain a day has significantly dropped and this has made it look like fees are now low on the network, if any popular project should announce something that will cause a really lots and lots of people to transact on Ethereum network again even if for 2 hours, we all will notice that the transaction fees will instantly hike again.
