When I first installed Linux, I was using the (default) setup, i.e. KDE and LILO. What I thought was nice was to be able to select on which OS I would boot next time with a handy menu.

When I switched to Debian / Xfce4 / GRUB, I noticed that this was no longer possible. From what I read on the forums at the time, I was stuck with the default option no matter what...
