How to choose web3auth SDK

Hi, everyone.
I am an engineer from Japan.

Please advise me on how to choose web3auth SDK.
I will implement MFA authentication in my dapp development.
I have read the documentation, but I don’t understand the difference between Modal-SDK and no-Modal-SDK.
How do I choose between them?

Also, can the core-kit-SDK implement all the MFA features that can be implemented with the plug-and-play-SDK (e.g. recovery by SMS or email, choosing which element to use for recovery, etc.)?

Thanks
