Cryptocompare is great for inputting a portfollio, and tracking the collective values, portfolio risk, etc. I really like the UI for this.
Coinmarketcap I find better for it's ability to see the Top 100, biggest gainers, social news, whereas cryptocompare is good better for analytics I find.
I'm also a fan of onchainfx that gives the option of useful tabs such as % down from ATH and annual ROI etc.
The more price tracking websites the better in my opinion! I'll use them all
