Non populated accuracy

Hello, I have the scenery tech landclass and utx, so I use utx for cities and st for vegetation landclass. Right now Im not overly impressed with the st landclass vegetation and rural landclass. It was supposed to fix the desert landclass problem in the usa, but when I flew into dfw the other day it was not nearly green enough. And I did find some small innacuarcys in some rural town in the west. Ive heard that xclass was better for cities, is fs genesis landclass the best for vegetation?
