With apt, you have to:
  apt-get update
first to pick up a fresh list of available updates,
then since the kernel has multiple versions doing:
  apt-get install kernel
will give you a list of available kernels.  You have
to pick the one you want from the list and repeat the
command with the version included.

Yum keeps headers for each package in a separate file and updates
them every time you run.  If a lot has changed it may take a long
time to pull all the updated headers.  Otherwise there shouldn't
be a huge difference and yum knows more about installing kernels.
Usually (always?) it will pick the right one and make it the boot
default.

It is up to rpm packages whether they overwrite config files or not
and in some cases neither way is right so apt/yum version upgrades
don't always work but they should be safe for updates within a release.
