Health coverage after losing my job: marketplace or Medicaid? (update)

I have 14 weeks left on my current insurance and I am comparing options. I am in Tucson, in case local advice matters. The COBRA notice arrived with a very high price. How fast did coverage start?

A free navigator at a community health centre walked me through my options. It took an hour and saved me a lot of guessing.

Compare the monthly price with the deductible. A cheap plan with a huge deductible can cost more if you need care.
