Is COBRA worth it after a layoff? - any advice?

I just got my COBRA paperwork and the deadline to decide is close. I do not usually post, so bear with me. I saw that marketplace plans might cost less. Did anyone switch mid-year?

A quick call to the plan's member line cleared up two things for us that the letter did not.

Check what the notice says about the election period and when coverage starts. Mine allowed a short window to choose.
