of course, this is all just other people's opinion ... and sometimes you just need to try something yourself.
I'm not impressed enough with the on-line reviews and various forum opinions to get the 24/28 f/2.8 - but I would have liked a lens in that zone. 28/2.8 AIS (0.2m) is the one that stands out. I went to the 16-35/4 VRII as my wide and it replaced my 20/2.8 + 35/2. The 20/2.8 doesn't get the most glowing reviews, but that said I've had it twice! Enjoyed it both times, but not blown away, I am really pleased with my upgrade to something much much more modern (N coating).
One option is to buy a used 28/2.8 or 24/2.8 ... try it, use it, like it, or hate it,
keep it, or sell it ... you should be able to sell a used lens for the around the same price. I call this free no rush rental (the risk is that Nikon bring out a G version while you are trying and the used value drops through the floor!)
