Any Nikkor 50mm that you can get your hands on will produce great photos, the best one for you is another story.

I would get the 50 1.8f again without thinking about it, I have that and the 50 1.4f and I only use the 1.4 because the 1.8 is an Auto Focus lens as far as I'm concerned both are excellent lenses that can take far better photos than I can. There are differences in the way the photos from these lenses look, but for me it does not matter. You may prefer the look of one of these lenses over another.
