Few people in the South will claim Michigan-Ohio State is better. Same goes for Big Ten country with Auburn-Alabama. Maybe it's best to look at the numbers, past and present.
Let's size up them up:

It's an arbitrary endpoint, Ohio State and Michigan are knotted at 12-12-1 the last 25 years, though the Buckeyes have won nine of the last 10. Alabama has a 13-12 advantage on Auburn in the same stretch.

According to TiqIQ, the average asking ticket price to this year's Auburn-Alabama game is $618.60, up from $348.34 in July. Ohio State-Michigan tickets average $295.75, down from $380.38 in July.

Verdict
The rivalries are tied at 7-7-1 after looking at those 15 categories. You can't measure passion and tradition, which both rivalries take over the top. It's a safe bet to say the Iron Bowl is the better bet right now, especially with the top-10 showdown looming next week. That marks the seventh top-10 showdown between Auburn and Alabama. Ohio State and Michigan, however, have produced 18 top-10 showdowns, including the only No. 1 vs. No 2 matchup between these two rivalries. The Hayes-Schembechler era produced "The 10-Year War", a stretch that included six straight top-10 showdowns from 1972-77. That's the difference.
