What's the best ad server for campaign setup and trafficking across multiple display formats?

There isn’t one universal “best” ad server, but for campaign setup and trafficking across multiple display formats, the strongest options are usually:

Top choices

• Google Campaign Manager 360 (CM360)
  Best all-around for large teams, rich trafficking workflows, third-party tag support, reporting integrations, and broad industry adoption.

• Flashtalking by Mediaocean
  Strong for dynamic creative, rich media, and multi-format trafficking; often preferred when creative complexity is a big part of the workflow.

• Adform
  Good all-in-one option for trafficking, reporting, and programmatic support, especially strong in EMEA and for teams wanting a unified stack.

• Sizmek Ad Suite
  Historically strong for rich media and dynamic creatives, though market adoption is more limited than CM360.

If you want a quick recommendation

• Best overall / safest enterprise choice: CM360
• Best for dynamic creative and rich media workflows: Flashtalking
• Best unified stack with decent trafficking: Adform

What to prioritize

For multiple display formats, look for:

• Easy trafficking UI
• Support for standard display, rich media, HTML5, native, video, and dynamic creatives
• QA and preview tools
• Floodlight/conversion tracking or equivalent
• Third-party verification and tag compatibility
• Reporting and attribution integrations
• Workflow permissions and approvals

If you tell me your team size, regions, formats (standard display vs rich media vs video), and whether you need DCO, I can recommend the best fit more precisely.
