I say honda activa is old and activa 4g is gold because honda activa has the trust of old one and gold features for new generations the honda activa 4g has the comfort while driving and good control even if I am driving fast. I fully rely on the honda aciva 4g even for long distance travelled.
Mileage of the honda activa 4g is great with 55 kmpl in the city road grip is the best as the old one but the appeal of the honda activa 4g is of 21 century.
