That's an interesting comparison between two famous fictional detectives. They're both highly intelligent in different ways:

Sherlock Holmes is known for:
- Exceptional logical reasoning
- Forensic and scientific deduction
- Physical observation skills
- Analytical thinking

Hercule Poirot is known for:
- Psychological insight
- Understanding human nature
- Methodical reasoning
- Keen understanding of human psychology

Most fans and critics consider them equally brilliant, just with different approaches to solving mysteries. Ultimately, they're both fictional characters created by brilliant authors (Arthur Conan Doyle and Agatha Christie), so there's no definitive "smarter" answer.
