This is one area where the comparison is more nuanced than it first appears, because the answer depends on whether you have live web access enabled.
Winner: Claude
When you've already gathered your research (from Perplexity, from the company website, from Google Alerts) and you need to turn it into a structured pre-call brief or stakeholder analysis, Claude consistently produces better analytical output. It's more structured, more complete, and better at identifying strategic implications vs. just summarizing facts.
Winner: ChatGPT (with browsing) or Perplexity
Claude doesn't browse the web by default. ChatGPT with browsing enabled can research a company live. Perplexity is even better for live research with source citations.
The best account research workflow: use Perplexity for live data gathering, then paste the results into Claude for analysis and brief generation.
Winner: Claude (with input data)
Given the same input data about a prospect, Claude produces a more strategically useful pre-call brief than ChatGPT. It's better at inferring strategic priorities from role context and company signals, and better at suggesting specific talking points rather than generic observations.
Use Perplexity to research. Use Claude to analyze. Don't use either in isolation for important accounts.
