I consider the Nikon 24-70mm f/2.8 as the best versatile lens with a large f/2.8 aperture, the range it covers makes it useful to shoot wide angle shots to shooting nice looking portraits. I tend to take this lens with me when I don't feel like changing the lens or don't want to carry any extra lenses with me, it's a good lens for general purposes.
The Nikon 70-200 f/2.8 is one of the lenses that I sometimes carry, I usually use to shoot portraits and panoramas, it's not the ideal lens to shoot objects that are far away since 200mm is not that far in my opinion and that's why I usually carry a Nikon TC-20E III 2x Teleconverter with me when I'm taking this lens. The photos I got with this lens were really sharp and the Bokeh looks beautiful when shooting at f/2.8 with this lens.
The Nikon 50mm f/1.4G was the second lens I purchased when I bought my first DSLR, at that time I only got this lens because of what photographers were saying about it and how great it is, and honestly I really did not like it when I was using it on my crop frame DSLR's, but when I bought my full frame camera I started using it much more and use it as my 'to-go' lens often.
