The Verdict
Perplexity wins for research. ChatGPT wins for creation. If your primary use is finding accurate, up-to-date information with source verification, Perplexity is the better tool. If you write, code, brainstorm, or need a versatile AI assistant for a wide range of tasks, ChatGPT is the clear winner.
