Having played TTS and some official DLC, I can say that a well-made fan creation will beat the usability/scripting of official DLC almost every time.

I found it best to search the Steam Workshop for the most popular version of the game I wanted to play. I also personally prefer "Scripted setup" games which automate a lot of the setup, though I know some people prefer the more tactile setup.

Odd, all I can say is that that hasn't been the experience of my friend-group, or my 50 year-old tech-phobic cousin. I haven't played the official Zombicide module mind you, I'm mostly sticking to games that are free in the steam workshop.
