Solution

A methoxy group is more activating than a methyl group in electrophilic aromatic substitution reactions because it creates a fourth resonance structure in the sigma complex. This additional resonance structure provides extra stabilization to the intermediate, which lowers the activation energy of the reaction and makes the reaction more favorable.
