The way the developer describes it, Vintage puts back in some of the ideosyncracies (read: "defects") that Room goes to great lengths to take out. Those peculiarities are considered part of the "vintage" sound, and that's why it was done, and why it was named "Vintage".
For myself, VRoom is so versatile and so difficult to make sound bad, I can't imagine using something else just because it more closely emulates less-sophisticated devices of yesteryear. Then again, I don't have VVV - for that reason - so I could be totally wrong. I just know that since I've had VRoom I've lost interest in looking at any other reverbs. I'm set.
