Here's why:
* "Better" is subjective: What makes a team "better" depends on what you value. Are you looking at:
* Overall record?
* Recent performance?
* Super Bowl wins?
* Offensive power?
* Defensive dominance?
* Playoff history?
* Rivalry: The Dolphins and Bills have a long-standing, intense rivalry, with both teams having periods of dominance.
* Fluctuating performance: NFL teams are constantly evolving, with rosters changing and performance varying year to year.
To get a more specific answer, you need to clarify what you mean by "better" and consider the specific context you're interested in (e.g., who is better *this year*, who has a better historical record, etc.)
Instead of focusing on who is "better", it's more fun to enjoy the rivalry and see how both teams perform each season!
