Insoluble metal oxide ensures that all the acid will get reacted whereas any excess insoluble metal oxide will not leave behind alkaline solutions (because it’s insoluble!)
This means that the pH of the resulting solution would be around 7 after complete reaction.
If we use alkali instead, an excess of the alkali will result in a pH level above 7.
