Both of the two options, closed and open-cell spray foam are great choices for insulation projects. Both have positives and negatives when it comes to their cell attributes. Open-cell foam is as it sounds, the bubbles (cells) are purposefully left open which makes it great for hard-to-reach areas, and gentle climates, and is wallet-friendly in comparison to closed-cell.
Closed-cell foam is best suited for extreme temperatures, aiding in structural integrity, and is even considered a vapor blocker. That means that it prevents mold, mildew, water damage, and the transfer of heat (vapor proof.) The closed-cell structure creates a very dense, hard foam.
