I'm using livecoinwatch.com a lot. More information and the possibility to built up a portfolio. But it's also kinda buggy.
You are spot on with livecoinwatch. This is the best I have found so far, in my opinion, much better than coinmarketcap. Very nice user interface, nice design, everything works as it is supposed. I haven't noticed any bugs so far, but the reason could be that I don't use it so much. Other sites of this type, but not as good, are CoinLib, CoinCap, CryptoCompare and CoinGecko.
