Sorry, forgot to mention that as a contractor you don't know how long contract will last. It may end in one week or may last 6 or 12 months. Contract work is always unpredictable.

There is no 'discount' or anything for Marketplace insurance, so the prices are likely similar to elsewhere.  One pro for Marketplace insurance is that there could be plans for your specific area, with your specific medical institutions.  That insurance MIGHT be lower than other plans.  On the other hand, if you go to a non-Marketplace agent, they may be able to point to a plan that meets your specific needs, compared to some areas Marketplace options may be limited.

One other thing to consider:  If your contract does end early, might your income fall below 400%?  If so, you might qualify for a credit when you file your tax return if you have Marketplace insurance.
