Health coverage after losing my job: marketplace or Medicaid? - what worked for you?

My employer coverage ended at the end of the month and I am trying to work out what to do as a customer-service rep. It has been weighing on me all week. I do not want a gap in coverage. What did you choose and how was the process?

Losing job-based coverage usually opens a special enrolment window, so check the deadline on the official marketplace site. I missed it by a day once and regretted it.
