GRUB is the Grand Unified Boot Loader and Lilo is the linux loader. Lilo is the early bootloader that came with linux and is still popular due to its simplicity. there are two problems with it. firstly it has a 4gb booting constraint limit and secondly it doesnot provide anykind of security at what parameters can be passed to the kernel and who can do that.

here is an excerpt from the site
GNU GRUB follows these requirements below:

Compliant with the Multiboot Specification.
Basic functions are easy for an end-user to use.
Rich functionality for OS experts/designers.
Compatibility for booting FreeBSD, NetBSD, OpenBSD, and GNU/Linux. Proprietary OS's such as Windows 9x/NT/2000/XP, and OS/2 are supported via a chain-loading function.
In addition to the requirements above, GNU GRUB has the following features:

Support multiple executable formats.
Support non-Multiboot OS's.
Load multiple modules.
Support a human-readable configuration file.
Menu interface.
Flexible command-line interface.
Support multiple filesystem types.
Support automatic decompression.
Access data on any installed device.
Geometry translation independent.
Detect all installed RAM.
Support Logical Block Address (LBA) mode.
Download OS images from a network.
Support diskless systems.
Support remote terminals. .

an added benefit of using grub is that you donot need to rewrite lilo to the mbr everytime you change the config file as opposed to lilo where it is required.

As far as i am concerned, i am a big fan of grub and hopefully tonight i will post my girlfriend's pic on the background of grub so that i start loving my pc more than ever. GRUB is a big yes yes for me and lilo is a no no. not to say that i hate lilo but just the personal preference.
