I use GRUB, exclusively. Never had any joy with LILO, probably due to my own fumbling, nonetheless. I must disagree that GRUB is hard to make changes on, it's simply a matter of adding lines or subtracting lines from the configuration file. You don't even have to run anything after making a change -- it simply works
If GRUB works, use it. If LILO works, use it. They're only boot managers (among many!!), not your OS.
