If not the best for now, I would recommend Binance. Almost all crypto exchanges would require a KYC verification, so you have to bear that in mind if you intend to be professional about your trading and investment plans.
Still, Binance recently terminated some trading pairs on its platform that paired with BUSD mostly, and if you are one who doesn't mind, it is a good option I would often recommend. That's also dependent on if the distinct difference between a decentralized network and centralized network don't affect your intentions for trade or investment in any way.
Theres also Bitget, but am yet to try it out or hear a great compelling review about the exchange.
Binance would have sufficed but considering OP’s preference for non mandatory KYC exchanges, Bitget like you suggested would be a valid option. I have read about a few reviews too–according to TokenInsights it is ranked as the fourth-largest CEX by trading volume in Q2 2023, its derivatives trading volume also had a surge. Additionally it is one of the few exchanges like Binance that has released its Proof-of reserves, and best known for being the largest Copy trading platform.
