Plane type matters too. Some planes are built without appropriate overhead space, I guess because we never used to take as many laptops/electronics? The newest planes from Boeing and Airbus seem much better for this. As in you can literally see claims of "60% more overhead space per passenger" on the newest planes and I've had no issue even on full flights with airlines that use newer planes.
