In my own opinion, I think that both transaction rates are fair enough, even though the fee for BTC might be so high. They both have speedy transaction rates and it is one good thing about both coins cos I don't have to wait for so much time to get my coins in my wallets or get it transferred to another. These two coins does it for me to be honest.
It's a question of preference as some will only use bitcoin to store value and others want to use it to send something abroad and then it is expensive.
