I would put it differently: it's fine to use `setq' on any variable,
it's just that there may be more to be done. You could therefore use
`customize-set-variable', but my preference is generally to view the
variable's definition, see whether a custom setter is defined, and
decide if I need to do anything about it.

It's not an error to use `setq' on variables with custom setters.

`customize-set-variable' is a function, so its arguments are evaluated.
In other words, it's like `set' rather than `setq'.
