What We've Actually Observed Using Both via Prompt Anything Pro
We've used both ChatGPT (GPT-4o) and Claude (Sonnet/Opus) daily through Prompt Anything Pro since 2024. The observations below come from real production use across customer support reply drafting, landing-page copywriting, and technical documentation analysis — not synthetic benchmarks. BYOK pricing means we pay API rates ($0.005-0.03/query) instead of subscription pricing, which changes the cost calculus entirely.
Cost reality at typical 'serious user' volumes (100 queries/day)
TieChatGPT Plus subscription: $20/mo flat. Claude Pro subscription: $20/mo flat. BYOK via Prompt Anything Pro at 100 prompts/day × 30 days: ~$8-12/mo on GPT-4o, ~$10-14/mo on Claude Sonnet. The break-even point is roughly 250+ prompts/day — below that, BYOK is dramatically cheaper. Above that, subscriptions may win on cost (but lose on flexibility).
Quality on customer support reply drafting (our highest-volume use case)
Claude winsClaude Sonnet produces drafts that need ~10% editing on average. GPT-4o produces drafts that need ~25% editing. The difference: Claude is more measured and less likely to over-promise solutions, while GPT-4o tends to add filler enthusiasm ('Great question!') that sounds off-brand. For B2B support voice, Claude wins consistently.
Quality on creative landing-page copy
TieGPT-4o produces stronger first drafts for headline + subheadline. Claude produces stronger first drafts for long-form body copy (300+ words). Our practical workflow: run hero copy through GPT-4o, then run body copy through Claude. Prompt Anything Pro lets us switch in one click per prompt — no need to choose one tool.
Quality on technical doc analysis + summarization
Claude winsClaude wins decisively on dense technical content (API docs, RFCs, academic papers) because of the 200K-token context window. We've fed Claude entire 80-page PDFs in single prompts — GPT-4o would require chunking. For one-shot summarization of long technical docs, Claude saves time and improves accuracy.
Latency on standard requests (typical 200-token response)
ChatGPT winsGPT-4o averages 1.2 seconds first-token, 4-6 seconds full response. Claude Sonnet averages 1.8 seconds first-token, 5-7 seconds full response. Difference is noticeable in inline workflow (highlight → prompt → response) — GPT-4o feels snappier. For batch / async use, the difference is negligible.
Bottom line
Don't choose. Use both via Prompt Anything Pro with BYOK — switch per-task based on the strengths above. The cost at typical volumes is lower than ONE subscription, and you get model flexibility you can't get from a single-vendor subscription.
