Agreed, and generally the advantage goes to the scope with the larger tube (e.g. 30mm rather than 1 inch). More room for the erector tube to be moved up/down and left/right.
In some cases there just isn’t enough vertical adjustment, such as shooting at long range (>100yds) or if the gun happens to have a barrel and scope rail that diverge. In those cases you either need an angled scope mount (“dropper mount”), adjustable mounts, shim between the rings and scope tube, or slightly arc the barrel.
