Quick answer

All three cost $20/mo. ChatGPT Plus: best for breadth (voice, image gen, custom GPTs). Claude Pro: best for coding and long-form writing (Opus 4.7, 500k context). Gemini Advanced: best for Google ecosystem and 2-million token context.

The three big AI labs all charge $20/mo for premium tiers. Which one is the best $20 you can spend on AI? Depends on what you do.

How to pick

  • Live in Google Workspace → Gemini Advanced
  • Write code professionally → Claude Pro
  • Write long-form prose → Claude Pro
  • Want voice mode + image gen → ChatGPT Plus
  • Use Sora 2 video generation → ChatGPT Plus
  • Want largest context → Gemini Advanced (2M tokens)
  • Want most features per dollar → ChatGPT Plus

Honest take in 2026: most casual users would not notice the difference. The marginal benefit of any one $20/mo over the others is small for everyday use. Match the AI to your dominant workflow.
