Should I move to Portland, Oregon or Sanfrancisco, California?

as the title asks....really. which city do You think is better? Why do you feel this way? What are some pros and cons? I have an opportunity to live in either place. I'm from Medford, oregon. Ive been living in Florida for 6 months now & I'm pretty ready to get out of here. Ive been to both Portland & Sanfrancisco. I like both cities.. good transportation, open-minded community, nature, trees.. lots of stuff to do. I'm torn between which city though,
