apt-get, yum or up2date

["Jan Houtsma" <list@xxxxxxxxxxx>]

In RH9 you only had up2date (as far as i know). Now i see people
saying: "don't use up2date anymore, but apt-get" Why? Has one
of these three tools big advantages above the other or is it only
what one is already used to and then advice others also to do 
the same?

Thanks,
