In my experience SDDM is superior in that it allows more flexibility in some respects, primarily in my use of two oddly positioned monitors. I have one atop the other. With SDDM there is no issue moving from one to the other gong straight up and down, not side to side. Also, and this could by now have been fixed or might have applied only to the applications I use, non-TDE applications seem happier with SDDM than they did with TDM. This may no longer be the case -- it's years since I used TDM -- but my system not being broke I have had no need to test alternatives.
I am glad to see that the kdesktop crashing issue appears to have been fixed. I'll find out whether that's the case here next time I reboot, probably in January.
