I would say that "WDW feels like a resort" has nothing to do with whether WDW is "better" - unless one's definition is that a resort feeling is what makes it better. Which has very little to do with "Disney" itself and much more to do with the offerings, space and services outside the parks.
I am fine with that definition, but just need to point out for the general readership here that other definitions are equally valid.
To wit...
WDW is better because it feels more like a resort (already stated by the PP)
DLR is better because the weather is better especially in the summer
WDW is better because it is much larger and has more parks
DLR is better because it is easier to navigate and does not require buses, boats or trams
WDW is better because of Epcot
DLR is better because it has been getting lots more new rides and shows in recent years
WDW is better because it has MyMagic+ and FP+
DLR is better because it does
not have MyMagic+ and FP+
WDW is better because it feels more immersive
DLR is better because it has better shows
WDW is better because I can spend an entire vacation there
DLR is better because it has the best theme park in the world -
Disneyland
One can go and on.
Having visited Tokyo Disney and Disney Paris as well, I can say all the resorts have things about them that are better than the other resorts. Taking one particular thing as the definition of "better" is likely to result in one not enjoying things as much as they otherwise might have.
