What's the best software for programmatic advertising in 2025?

Hey everyone,

I’m in the process of evaluating demand-side platforms (DSPs) for running programmatic ad campaigns and wanted to tap into the community for real-world feedback.

We’re looking for a platform that helps us:

• Run cross-channel ads (display, native, video, CTV)
• Access premium inventory via RTB
• Segment and retarget audiences effectively
• Gain clear performance insights with actionable reporting

So far, a few names keep coming up as per G2's category:

• The Trade Desk- Seems like the industry standard. Is it manageable for non-enterprise teams?
• StackAdapt- Great UI, strong native and video support. Anyone using it for B2B or D2C?
• Basis Technologies- Comprehensive features- how steep is the learning curve?
• Criteo Commerce Growth- Strong on dynamic retargeting, but is it flexible enough beyond ecommerce?
• Choozle- Budget-friendly and self-serve. Curious if it’s too limited for scaling.

Real-world insights on ease of use and setup? Campaign performance and ROI over time?
