cms is not admin, as there are some write. just admins in Lara full to the brim, and is not even close to cms.
cms is more support for themes and third party plugins ready, and IPAS for their work.
and cms it's more the ecosystem of the plug-ins. you can easily put and get ready to work the site almost without programming, or at all.
from cms october perhaps nothing, although it is very specific.
but if you plan to program it is best to take it to the admin panel.
if it is good, but nova is not cheap or free and good owladmin for example.
