That is fair. I was also born after VII, and only knew the OF until I discovered the EF.
If you want to see why I contend aspects of the EF are simply better, see this link:

It compares the two forms of the mass, side by side. If you only have a short amount of time to read it, just skip to the Offertory and compare the two. That is what sold me on the idea that the prayers of the EF simply are more rich and, in many cases, express our Western theology more clearly.
In terms of advantages in the OF. I would say that the main advantages are:
-
some vernacular
-more acceptance of vocal participation for the laity
-the ability to chant the Kyrie with tropes (which was regrettable surpressed after the Council of Trent)
-more readings (though this is a toss up; there are strong advantages to both the OF and EF lectionary)
-removal of the words “the mystery of Faith” from the Words of Consecration
-additionally, the OF Divine Office is a great improvement for extremely busy secular priests and laity who wish to pray the Divine Office
There are probably more that I could think of, but those are just off of the top of my head.
