Where do 2023 Michigan and 2022 Georgia fall in the pecking order of the past recent undefeated teams?

From the 6 years between 2018 to 2023, 5 of the national championship winners have won the title undefeated: Clemson, LSU, Alabama, Georgia and Michigan in that order.

We all know 2019 LSU is hands down #1 out of this bunch but where do the other undefeated teams fall 2-5?
