Hi, i have the 50/1.4G lens, and find it to be a nice sharp lens, that focuses quite fast with very little dithering once locked on. I use it with a D4 and a D700 bodies. At f1.4 the dof is very narrow as one should expect, so focus should be carefully done using the back focus button and continuous focus settings on the body. I would also suggest you use single point focus rather than multipoint focus to make sure it af on the correct spot of your subject.
Looking at your equipment list, I have had 3 of the Nikons listed, and also the M3, but currently use the M6TTL and M8 rangefinders.
50mm 1.4D lens here. I bought it because everyone and ever site i read said i needed one. But i have probably taken less than 100 shots with it. I do love the OOF blur and it is sharp. So when i have used it i am impressed.
Sorry didn't see that you were asking about the G version. Well thats my opinion.
I've had all the auto focus 50's and the G is by far the best. I use it primarily wide open or when I just want something less obtrusive than a zoom or when I don't want flash. However, it is sharp and the focus is accurate. When shooting hand held wide open I find single point continuous auto focus the best.
I like it a lot, although I don't use it very often because my 24-120 f/4 is sharp enough for most of what I do, and more convenient. But here's one example in which I felt the 50mm was needed, as I was seeing some flare when I tried to shoot the rising sun with a zoom:
