There are several ways to recall and save factory and user settings for both Logic Pro X’s individual plug-ins and entire channel strips. There are three levels of preset organization, and primarily using the top-level approach—as Apple intends—is fairly straightforward.
Honestly, patches may have a little more of a learning curve. However, they provide the most flexible and powerful options for preset management in Logic. Furthermore, the plug-in settings are still the best way to manage individual plug-in tweaks, and channel strip settings are the most straightforward way to load instruments and effects without potentially affecting other mix settings.
