Both rivalries are intense, but I think the Packers vs. Bears rivalry has a bit more history and significance. It’s the oldest rivalry in the NFL, with decades of memorable moments, and the teams have always been competitive within the NFC North. That said, the Cowboys vs. Eagles rivalry is incredibly heated, especially with both teams consistently battling for NFC supremacy. I lean toward Packers vs. Bears for the history, but both are thrilling in their own right!
