NO, with today's high ISO camera's 1.4 lenses are a thing of the past. There is less than a 1/2 stop between those two lenses. The Nikon 50mm 1.8 G lens is outstanding. There is NO, I repeat, NO difference in image quality between the two lenses and don't let anyone tell you their is. Go 1.8 and be happy. And, it is currently on sale.
I own and use both lenses. Unless you have an overriding reason (i.e. a lot of very low light shooting) to buy the 1.4, the 1.8 will serve very well.
However, the statement above has 2 errors. The 1.4 is 2/3rds of a stop faster, and will have a slightly shallower depth of field. The resulting bokeh will be different. If the 2 lenses are compared at the same f stop, I doubt you will be able to tell any difference.
