Are Binance and OKX the same?

Could you please elaborate on the differences between Binance and OKX? I've heard they're both major players in the cryptocurrency exchange market, but I'm curious to know if they offer similar services or have distinct features that set them apart. Additionally, I'm interested in understanding their respective reputations in terms of security, reliability, and user experience. Are there any notable advantages or disadvantages of using one platform over the other? Thank you for your clarification.
