My working hypothesis is that EFI is the future so I use it when I can. I am frequently disappointed to discover how clunky an implementation's user interface is.
If I remember correctly what I was told, the EFI shell cannot be delivered with machines that have Secure Boot. Or maybe it is with machines that have the Windows Logo, at least recently. So I don't think that current machines come with an EFI shell. I don't know if an EFI shell is generic -- would work on all machines with the same architecture.
I don't remember see Secure Boot in the BIOS for the current machine. So, maybe, EFI can be run with or without Secure Boot. -- William
