Answer 1

It depends on your needs. Use QStandardItemModel if you just want to store custom data and don't want to write your own model logic. This one is generic, you can use it for custom data without subclassing.

On the other way, if you wish to write your own model logic, then choose QAbstractItemModel. It is abstract class. It means, it has no behavior implemented, it is just an 'interface'. It tells you which methods your model should implement, so it can be used as ano other ItemModel class in Qt.
