Lots of variables to consider and not sure if it truly matters/is a productive topic to discuss. The bombs on Dresden were probably much less accurate/more random, but in return it also had far fewer inhabitants (roughly 630k at the time, less now).

For me looking it up it was kind of suprising though, how close the area size is between the two. I knew Gaza was small, but the direct comparison helps to put it into perspective, especially when you consider that they can’t really leave.
