The California Department of Forestry and Fire Protection, better known as "CalFire", maintains a Top 20 Most Destructive California Wildfires list. The list is accessible in the "General Information/Links" box at https://www.fire.ca.gov/stats-events/ (note that the address of the list itself changes as the list is updated).

Two active fires have already destroyed enough structures to place in the top ten on the list. The LNU Lightning Complex is currently shown in 10th place on the list with 1198 structures destroyed. The CZU Lightning Complex, while not appearing yet on the list, recently surpassed LNU and has destroyed 1361 structures, enough to rank 9th.

Will the CZU Lightning Complex be ranked ahead of the LNU Lightning Complex on the destructiveness list once both are extinguished?

This question will resolve positively if the CZU Lightning Complex is ranked higher than the LNU Lightning Complex on the list when both fires have been extinguished, and negatively otherwise.
