They solve different problems. UGC gives you depth: one creator walking through a story, a demo, a before-and-after, with room to handle objections properly. Street interviews give you width: many real reactions, built-in social proof and dozens of natural hooks from a single shoot day.
In Curve.no client accounts street interview creatives typically outperform standard UGC on cold traffic, often around 2 to 3x on ROAS, while UGC earns its keep deeper in the funnel and on angles that need explaining. Strong accounts run both and let the testing data set the ratio.
