AFAIK Ubuntu's default is "GRUB_DEFAULT=0" (it's upstreams's default) .

"GRUB_DEFAULT=saved" is useful/functional if you've used
"grub-set-default" or "grub-reboot" to set the default grub entry or
if you've set "GRUB_SAVEDEFAULT=true" (which is unset by default and
which you need to set in order for grub ro re-use the last menuentry
