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

I was offered COBRA and the monthly cost is more than I expected as a line cook. This is my first time dealing with any of this. My old employer will not help with the premium. Is the decision time really that tight?

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.
