There is "stretch", which is equivalent of more known as LTS of Ubuntu: 
5 years. And then, there is easy in place upgrade from regular or 
"stretch" to next release.

But no, I will not argue against uniqueness of 10 year life cycle of 
RedHat. I just said that my life [with Debian] will be no bigger hassle 
than it was [with CentOS].

The only difference of Debian is: it has vast collection of everything, 
so you really need to make your own choices. But if it's done once, you 
can in one go tell next installation to install all the same software 
(packages). Of course, I, being a simple guy, had much simpler life with 
CentOS, just choose all software groups that sound relevant... (jus 
grossly exaggerating ;-) But with huge collection like Debian one (or 
like FreeBSD ports are, or macports for MacOS) once you spent time 
shaping system to your preference, you are done, and all next systems 
are rather routine, almost as unattended as RedHat/CentOS kickstart 
install is.
