Which site are people using most to check prices.  I've generally been looking at coingecko but there does seem to be a price difference when looking at coinmarketcap.

Look at the price at the moment for ETH/USD:

https://coinmarketcap.com/currencies/ethereum/        $1,258.93 USD (2.29%)

https://www.coingecko.com/en/price_charts/ethereum/usd        $1,290.21

Quite a difference! Which one is more accurate?  Or another site?
