These are different shingle formats, but format alone does not determine whether a product suits a particular roof. Product-specific requirements, the complete assembly, and appearance should guide comparison.
What to do next
Ask for the exact proposed product rather than a broad category. Compare accessory components, installation documentation, and warranty conditions. A meaningful bid comparison includes the surrounding roof system, because a new field shingle does not resolve every transition or ventilation issue.
