What are the data sources that you guys using?

Where do you guys get reliable and accurate crypto data? I usually google and compare the data of different sites (some of which are DeFiLlama, Dapp Ranking, The Block Crypto) but often there are mismatches. And it's also hard to compare different chains/dApps together due to missing info or I'm not sure the way different sites calculate data. For example, to compare the gas fee of different chains, I have to search for data from different sources and it took quite a lot of time.

Do you experience similar issues/questions? What info source to get all the info are you using?
