Just my 2 cents, but no, you're not. RH has better updating support and now you can use apt-get and synaptic to upgrade packages and kernels or to remove them. It keeps the grub.conf files updated when kernels come and go and lots of other stuff. It does a great job. MDK update site never has packages available for me, so updating is very frustrating. RH and freshrpms sources have always been up for me and fast too. Usually 100kbs+ on my cable modem.
Check out this article on how to install and use apt-get, synaptic, ogle dvd player, etc. with KDE on RH 8.0. http://www.osnews.com/story.php?news_id=1890
PS, I've installed 8.0 so many times now I just go to this article and cut and paste the commands into the shell (yes, you can do that in 8.0) and have apt-get, synaptic, xmms mp3 working, ogle installed,etc, in about 10 minutes. Apt-get and synaptic are a must for 8.0.
