Binance KYC is the best here. It's almost instant as long as requirements are met. KYC verification isn't also compulsory, it's only needed for increasing daily limit and withdrawals of fiats
well I first learned about this exchange binance from Airdrop which I worked on for a very long time and at that time to get the reward I had to complete KYC, and well it was very fast and smooth and until now I still use it because I think it suits me personally
