Yeah, because I'm sure Marvel's NYC doesn't have any of it's own major landmarks unique to the Marvel Universe.
But going off what Vordan said when it comes to putting in effort to fictional cities. Real cities being often feel interchangeable in comics because writers rarely actually try to build off the culture and history of that city to make unique to their character/story. Real cities like Boston, New York, New Orleans, Pittsburgh, Detroit, Las Vegas, San Diego have far more interesting histories and culture to them than any of DC's fictional cities ever will. So that's why I don't there's really any argument beyond personal preference/experience of whether using fake or real cities is superior to one or the other.
