What is the NFL's Equivalent Rivalry?

I like that the nationally relevant NFL rivalries cycle. For example, I like what's brewing between Seattle and San Francisco right now.

Jets/Pats is a big rivalry because of Boston/NYC...but the Jets suck. Packers/Bears is generally regarded as the most historical, but it's not that big of a deal compared to other divisional rivalries.

But Lakers/Celtics was all about championships, not regular season wins. Imagine if the Super Bowl was Dallas/Pittsburgh or Giants/Pats for 7 out of 10 years or something...then it would be comparable
