“Not that difficult” but still more difficult than being able to boot without a separate live USB drive.

True, but… When MBR Grub drops to rescue or doesn’t appear at all, it’s not only difficult (at least for newbies) but somewhat random if you can actually boot a given OS. With EFI Grub, I’ve often managed to boot using BIOS boot override to launch a usable Grub configuration.
