Is COBRA worth it after a layoff? - 4 weeks in

I was offered COBRA and the monthly cost is more than I expected as an insurance claims processor. I worked as an insurance claims processor before this. I saw that marketplace plans might cost less. Did anyone switch mid-year?

I priced both side by side: total yearly cost, doctors in network and the deductible. Marketplace was cheaper for us, but only because our doctors were covered.
