I have experience with two different laptops: 1. Dell enterprise laptops generally have a robust EFI system which allows for all kinds of `.efi` files to boot on `vfat` partitions. Dell laptops also have a good firmware setup for stuff like mokutils to work so that people can use measured boot with their own version of linux. They also work extremely well with self-encrypting nvme drives. 2. HP consumer laptops which are the worst of lot and essentially prevent you from doing anything apart from stock configurations, almost like on purpose. 3. All other laptops which have various levels of incompetence but seems pretty harmless.

For all laptops apart from Dell, Grub is the bootloader that EFI could never be.
