I have the mini one and like it. But you have to create your own content for it or find a temple to print out. I like the screen DM David put together for TWGS mini:

But I ended up making my own in MS Publisher.
I find that as I get more used to a system, a lot of the stuff on most DM screens is in my head and I just don't need it. Also, I use some third-party stuff, so I like to add references to that, as well as some campaign specific info. For D&D, as I use D&D Beyond now, and am far more familiar with the rules, I find I am using the screens for campaign-specific references. That's one great thing about Hammerdog's TWGS, you can easily swap out inserts. So you can have not only system-specific inserts, but also campaign specific inserts.
For example, I can have inserts with pre-generated names for different regions and I can swap out them out from session to session as the party travels. Also, if I know some rules are going to be important for a specific session, I can create a reference insert for just that session.
So, yes, if you customize a lot and don't mind spending the time to create your own references, TWGS is handy.
