Health insurance gap after a layoff after 15 years as a call-centre agent

I have 15 weeks left on my current insurance and I am comparing options. I have been trying to stay organised about it. 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.
