I'm using both the the MBA screen (9C8F no lines) and 13" MBP screen (9CBD). The MBA does have a better viewing angle, but that's due to the absence of glass panel. Both screens are decently bright, but you can also see that neither is the most color accurate (being TN) display on there. I do feel that the glass on MBP adds a deeper tone on blacks, which makes the overall viewing more comfortable. However, the MBA's screen wins in useability in most conditions, because it is not nearly as reflective as MBP's glass display.
