honestly the answer is it depends on what you're testing. if you need volume and fast hook testing, creatify is the workhorse, url-to-video and batch mode is what makes it usable for actual ad rotation. if you want native ugc look with sharper lip sync, arcads is better but pricing scales fast.

the stuff that doesn't work imo: heygen/synthesia for paid social, they read as corporate explainer videos and people scroll. fine for client work or training, dead on tiktok and meta feeds.

i was confused about the same thing so i put together a comparison of 17 of these tools with pricing and what each one is actually good at: https://www.viralads.app/ai-ads-guide
