Is COBRA worth it after a layoff? after 6 years as an electrician's helper

I was offered COBRA and the monthly cost is more than I expected as an electrician's helper. This is my first time dealing with any of this. My old employer will not help with the premium. How did you decide?

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.
