“Games against similarly skilled opponents and with similarly skilled teammates tend to be the most fun.” - Bungie

I disagree with that statement. I find that games against slightly less skilled opponents are the most fun. On Wednesday, I had some great scores and my level went from 4 to 5 after the first game on Saturday. Then I started to play against opponents whose level was between 5 and 10! It was really bad, and my level went back to 4. How depressing.
