FF4 did more. Unless you're talking about popularity and how many games it sold which would be silly to consider for a best list. Before FF4, I remember having to grind in every RPG and none of them being worthwhile for story. After FF4, you had to grind in almost no RPG and it became expected for RPGs to have a huge focus on story. FF4 was the game to first give us ATB, which FF7 continued to use. FF4 was the first RPG I can remember where the soundtrack was amazing. After FF4, it felt like that became a requirement for all in the genre.
FF4 was more of a leap and more mind blowing for its time than FF7 was for its time.
