Is COBRA worth it after a layoff?

I just got my COBRA paperwork and the deadline to decide is close. It has been weighing on me all week. I saw that marketplace plans might cost less. Is the decision time really that tight?

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

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