Another point for flings. Meaningful relationships can be terrific. To be able to share in each other's hopes and dreams and to know someone so well that you both know what each other is thinking. Also to consider your partner as your 'best friend' is a truly rare and wonderful experience. Also it will not be accumulating any points either so you can stop keeping track.
Meaningless flings can also be terrific.
Usually flings do not last long. That is the whole premise of a fling. If one wanted something that was lasting one would be looking for a relationship not a fling. However flings can sometimes last longer than either party ever anticipated. A few years ago I had a fling with a young lady.
