Pick Perplexity Computer if...

✓Higher output quality (9 vs 7.5)

Professionals and small teams who will burn $200/month worth of research, drafting, and multi-step workflow time -- consultants, researchers, analysts, founders. Especially strong if you want frontier models across text, video, and images in one agent without stitching APIs together. The right pick if infrastructure is a non-starter and quality ceiling matters more than cost.
