Preferably coingecko is the option I choose most of the times, but there are a few tokens whose information can't be found there then I rely on other sources for getting the prices and other info.
Coingecko is having a lot of options to choose from to show the price like hourly data etc. Coinmarketcap is the older amongst both and before coingecko became popular I used to go to coinmarketcap for getting the price info and all.
