You can use both. I normally create ISOs like this:
# mkisofs -R -l -J filename.iso directory

Actually, because I usually want the CD created with the files in a 
subdirectory on the CD, I usually use something like
# mkisofs -R -l -J -graft-points filename.iso /dirname/=/directory/

You only need -J if at some point you might try to mount the CD under 
Windoze.

If you are making backups, you are probably better off using -R instead 
of -r, so that file ownership and permissions are preserved. If handing 
the CD out to other people, then the -r is better.
