Reels?

I've heard so much mixed advice. Currently mine is sctructured showing 2-3 shots of each project with text below saying what the project is. Was told this was the way instead of a mashup essentially showing off the cinematography of what I worked on.

For context I am still pretty green. 3 years out of college, non-union, looking to get into docs. The biggest thing I worked on was a doc series. What do you think? Is a portfolio more important?
