I wanted to wait to comment on this thread until I really spent some time with a Gottlieb EM. I spent most of this afternoon disassembling and cleaning Gottlieb Decagon units for the first time. They are more time consuming than a Williams but I was able to pick up speed the more I did. To help with the annoying flat head screws I bought three new tools. Two Klein screwdrivers (3/16 and 1/4) and a magnetizer. I got these at Home Depot. I have several Craftsman screwdrivers and I found their tips to be less squared off and not as "fat". This led to more slipping for me. All the tips I had for my ratcheting screwdriver had the same issue. The magnetized (yes, the magnetizing did work) Kleins made the job a lot easier.
