Really depends on the context.
QtQuick has the advantage that is allows you to have all kinds of animations, e.g. when the list's content changes.

Of course it requires a different skill set, so you'll have to put quite some time into learning it properly.
If you are already good at using Qt's C++ API you might get further faster using a QListWidget or a QListView with a custom item delegate.
