In fact, a 2017 study by FoodPulse found that Grubhub was used more than any other food delivery service, with UberEats coming in second.
One reason for this may be that Grubhub offers a wider variety of restaurants than UberEats. Additionally, Grubhub offers a more personalized experience, with users able to customize their orders and read ratings and reviews from other customers before making a decision.
