I was just recently blown away by what I can accomplish with the Debian installer on getting Debian installed on a system. I used to think that the openSUSE installer was the most flexible Linux installer, with Anaconda running a close second, but I think I’m going to at least put the Debian installer in a 2-way tie for first with openSUSE. The only reason I would say that, is because the openSUSE installer uses a hub-and-spoke design to installing the operating system. This means you can pick and choose what you want to install, rather than going through the entire installer itself. Further, the openSUSE installer supports installing from a SMB share on a Windows network, with neither Anaconda nor the Debian installer support (that I can tell).
