That's a fascinating question that detective fiction fans have debated for decades! Both are brilliant fictional detectives, but they showcase different types of intelligence:

**Sherlock Holmes** excels at:
- Deductive reasoning and observation of physical evidence
- Vast knowledge across many fields (chemistry, anatomy, literature, etc.)
- Seeing patterns others miss
- Dramatic, lightning-fast conclusions

**Hercule Poirot** excels at:
- Psychological insight and understanding human nature
- "Little grey cells" - methodical, patient analysis
- Getting people to reveal themselves through conversation
- Considering all possibilities before reaching conclusions

It's like comparing a brilliant scientist with a master psychologist. Holmes might solve a case faster through physical clues, while Poirot might catch a criminal Holmes missed by understanding their psychology.

Most literary critics consider them intellectual equals, just with different approaches. Holmes is more flashy and immediate; Poirot is more subtle and thorough. Both have solved "impossible" cases the other might have struggled with.

What do you think? Does one detective's style appeal to you more than the other?
