Without KYC my favorites are TradeOgre, Exbitron (new altcoins) and Coinex. Coinex is more modern and KYC is optional. They only ask for it to participate in airdops/promotions. But Coinex saves your ip when you log in to prevent account theft.
TradeOgre and Exbitron don't even have a KYC option.
Volume there isn't even a lot so if you think that they're good and the coins that you're trading there are still manageable to trade, that's you.
But for me, I don't think that I'll trade there, they may trying hard as an exchange but it seems that after a long time in the market, still they don't have their break and they need to do something about it if they're serious. If there's no kyc there, they better remain that rule.
