Yes I understand what you mean. I am also still using CoinMarketCap.com, but will probably change soon as there some alternatives. Didn't explore them yet.
On my twitter someone suggested: https://www.livecoinwatch.com/
Where you can easily turn on and off the korean markets, but I think they also don't have the value of the coins against ETH.
On http://coincap.io/ you can find the functionality you talk about.
Do you know any others of interest?
I do not sadly, I will continue using coinmarketcap as its easy and on point. On coincap.io u need to do a few more clicks to find out eth value and is not that user friendly.
I like cmc tbh for these reasons but I dont like that they are not transparent with the users :/
