COBRA quote is huge, any alternatives? after 9 years as a web developer

I just got my COBRA paperwork and the deadline to decide is close. I have read a lot of threads here and could not find my exact situation. 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.
