No favorites yet since we have to see how reliable they are.
Another problem with some of these sites is that they are usually relying on one source for price which is not a direct exchange either. For example btc2fiat and preev.net are 100bit look the same and all seem to be using coingeko for their source. myri.io is short and looks the same but uses only bitstamp.

Any good alternative, in my opinion, should have a short domain name that is easy to remember and fetches the price from multiple sources all being actual bitcoin exchanges. Not third party APIs like coingeko, coinmarketcap, etc. and maybe no altcoin exchange like Binance.
Some sources could be: Bitstamp, Coinbase, Kraken, Gemeni
