Health coverage after losing my job: marketplace or Medicaid? - any advice?

My employer coverage ended at the end of the month and I am trying to work out what to do as a teaching assistant. It has been a long 19 weeks. The COBRA notice arrived with a very high price. What did you choose and how was the process?

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