What are the best boot loaders/managers?

What are the best Linux bootloaders?

Pros

Pro
Easy to install and setup

Only requires 2 commands most of the time (i.e. grub-install ... and grub-mkconfig ...).

Pro
Support for a large number of Operating Systems

Grub can load a large number of operating systems, not just Linux.

Pro
Easily locates a kernel file

Grub is very file-system aware. This way, it can easily locate a kernel file which is residing in the file system without having to specify a logical-sector.

Pro
Has an interactive CLI

Grub has an interactive command line interface which can be very helpful at times if anything goes wrong during the boot process, especially after a fresh install or after a kernel update.

Pro
Supports BIOS

Has BIOS support unlike other bootloaders which only support efi or uefi.

Cons

Con
Slower boot times

Grub has slower boot times than most other bootloaders.

Con
Fully-featured also means harder to wrap your head around

Grub has a lot of features that other boot loaders may not have. But this also means more time spent on the documentation if you want to know the ins and outs of it.
