I am a self-started UX Designer and building my portfolio to get new opportunities. I have been seeing some great UX portfolios: 

* some UX designers have documented all deliverables and they made each project like a story with sketches, wireframes, charts and pictures of final products (such as web/mobile app)
* some simply describe what they did, what take-aways they've got from these projects.

I'm wondering which is better.

**Context:** I have a background in Computer Science, but I figured out I didn't want to become a pure programmer. It's not easy to compete with UX designers who have solid design practice and HCI background, and it seems my shift-away from programming becomes my disadvantage (although I think my Computer Science background is an advantage when it comes to conversations with engineers). 

**Which portfolio presentation method would better show this CS background to my advantage?**
