I believe making proper sense of FCs and the seemingly arbitrary at first glance rules of hooks requires knowing the underpinnings of how hooks get called. In class-based components “didMount”, “willReceiveProps”, “willUnmount” et al. would be more or less intuitive to a newcomer with just a general idea of how it works. That I believe makes FCs fundamentally more complex to learn from scratch. Personally having some experience I go with FCs if there’s a new complex front-end project that is based on React, but I use class-based components if I need to sprinkle a few on a mostly static website that may have to be maintained by someone else. (Class-based components in a basic case, which would be the case in question, are also quite straightforward to convert to FCs.)
