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 call-centre agent. This is my first time dealing with any of this. I do not want a gap in coverage. Is there help filling out the forms?

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