Convenience to find the food you are looking for and the locations of those kiosks are important.
To be honest, there is no question about this one and I’m going to tell you why Epcot rules this very easily even with the disappointing closures of many kiosks around World Showcase.

It should be easy to find what you are looking for and to their credit, each kiosk or location has a number on it that coincides with the map. The problem? They are not all easy to find. I spent a good 10 minutes trying to find kiosk number 12 and walked back and forth between 11 and 13 until I happen to see it stashed behind a building on the lakefronts edge.
There are 18 kiosks and while most of them are pretty close together, two are out of the way. One has pretzels and the other has chili fries. I didn’t bother making way all the way back to the Key West area to try to the chili fries. It just seemed too thrown together and more than a couple of venues were located inside restaurants and even a bar. Sloppy.
Epcot
Even with COVID you can’t help but love the F&W layout as you traverse the World Showcase from one side to the other and there are more kiosks spread around the Port of Entry (the fancy way of saying entry to World Showcase).
The only thing really disappointing was there were too many closed venues and that was a drag but outside of that, they were easy to find.
Advantage: Epcot by a mile
