Impossible to compare until the wano war ends, marineford is ALL about the war, wano is what? 3-4 chapters that the war is going on. It have potential to be a better war with the portrayal of kaidou, SN, F6, Calamities, SH, scabbards being good and who ever comes like Marines, Cp0, great fleet, revolutionary army, weevil...etc help the war gets better too.
Of course NOW...theres no way to compare,the fights didnt even truly started yet, Just the First clashes.
