What is the difference between BEP20 and BEP2?

Could you please explain to me in detail the fundamental distinctions between BEP20 and BEP2? I've heard about both tokens but am somewhat confused about their unique features and applications. Could you highlight the key differences in terms of functionality, compatibility, and maybe even their significance within the broader blockchain ecosystem? Additionally, if possible, could you provide any insights into which one might be more suitable for specific use cases or investment strategies? Your clarity and expertise in this area would be greatly appreciated.
