It is more time consuming, waiting for compiles for every package installed.
But, you learn things you'd not likely ever learn otherwise, and the result
is you have more control and knowledge of your system, and a lot less
installed software that you'll never use.

Debian's LTS nature can be a compelling reason for choosing it.

My favorite package manager was the youngest around until Fedora 22 was
released, when Yum was replaced by DNF, making DNF the newest. I find
openSUSE's Zypper and YaST2 combination unbeatable in terms of power, ease of
use and friendliness. Zypper is cmdline only. YaST2 has ncurses and GUI
modes. Both use the same RPM foundation and databases, so they can freely be
switched between, just not both run at the same time. Their package locking
system is simple and easy to use yet as powerful as anyone could hope for.

It doesn't matter when. AFAICT, default.target has no effect on anything
already running.

Note that there is both the original Grub, now typically called Grub Legacy,
and Grub2, which some distros call Grub while others call it Grub2. The newer
is significantly different, much more powerful, and much tougher to deal with
manually if manually is your pleasure for configuration management. Grub
Legacy doesn't support EFI, can be tricky or impossible to use with storage
capacity >2TB, but doesn't cry the sky is falling when you wish to install it
to a partition instead of MBR, nor complain when a vga= is on cmdline. Grub
is my primary bootloader on every one of my many systems, always on a primary
partition, never the MBR. Grub2 here is only ever installed to Debian or its
derivatives, and not used to actually boot except when wanting to select a
prior kernel version to boot.

I don't think very many distros use /etc/sysconfig/ any more, if they ever
did. I do think on openSUSE it's used mostly or entirely by YaST2.

It seems distros are more and more catching on that /etc/ is where sysadmin
deviation from default configs belong while defaults belong in /usr/ along
with the software.
