What's the best creative review platform for collecting and approving billboard creative files across a busy ad ops workflow?

For billboard creative review and approval in a busy ad ops workflow, the best fit is usually a specialized ad-ops / creative QA platform rather than a generic proofing tool.

Best overall pick: Ziflow

• Strong visual review and annotation
• Good version control and side-by-side comparisons
• Works well for multi-stakeholder approvals across traffic, creative, client, and legal
