Which AI Model for What

After years of daily use across all three major platforms, here's what I've learned actually works:

Claude - When personality matters

Best for: Client-facing writing, blog posts, anything where you need a distinct voice
Also excellent for: Code (better than the others), math and numerical reasoning
Limitation: Struggles with Word document editing/formatting. If you're working in an existing .docx template, use ChatGPT instead.

ChatGPT - When you need continuity and document work

Best for: Editing existing Word documents, ongoing strategic conversations (longer memory)
Also good for: Quick answers, maintaining context over weeks
Limitation: Writing tends toward corporate/generic. Fine for internal docs, but you'll rewrite client-facing content. Also notoriously unreliable with math and numbers — don't trust it for calculations or numerical analysis.

Gemini - When you need real data

Best for: Questions requiring current information ("What's a 4 WAR outfielder worth in free agency?" "What are current cybersecurity compliance requirements?")
Also good for: Fact-checking, market research, technical specifications
Limitation: Least personality of the three. Great for gathering data, less great for synthesizing it into compelling narrative.

What about everything else?

For specialized tasks:

Image generation: Nano Banana Pro (formerly DALL-E 3) is currently the best option
Transcription/voice: Most platforms now include decent voice features
