To add to this article, there are some bits in the Documentation part of the change proposal. Some information is already obsolete though because of fast pace of development of SDDM. To conclude, the main reasons are the CLA which is a participation blocker for many people and better outlook on future maintenance (for us, used to KDE codebase), as it's written in C++ and Qt, compared to C and Glib in LightDM.

I thought I recall reading a plan about kde moving to lightdm at one point?
Perhaps you could mention the reasons SSDM was decided over lightdm-qt?
Not up to date comparison - http://aseigo.blogspot.cz/2013/03/logging-into-plasma-workspaces-2.html Martin knows more about decision later, I can see Canonical's CLA and future Wayland support as the main reasons.

This might be of area to other spins that use lightdm currently and might wish to look at SSDM too.
Thanks,
