1. I shoot raw only.
2. I connect the cable to my camera, and use ViewNx2 to upload (transfer) images from my camera toViewNx2. For me, it is fast. After upload, I format the SD Card in the camera.
3. I do not edit in Nx2. After transfer, and doing what I want with Nx2, I close it, open up Bridge, and then work on the .nef files in ACR, and then PP in PS or other editor of my choice.
Why I like to use ViewNx2:
a. With Nx2 open, I have the Nx2 Browser on the left, and Adjustments and Metadata on the right. Any questions about Metadata or quickly confirmed.
b. I can quickly see the Focus Point(s) if I want to in the Image Viewer (Main Window in the center).
c. I can send the image that is open in Nx2 directly to PS CC if I desire, or other programs I select.
d. I have a "Filmstrip" open at the bottom, showing all the images from the upload. I can delete and rate images in the Filmstrip. I can delete multiple images all at once if desired. I like to use the Filmstrip to choose which image I want to look at, or with arrows below, I can move forward or backwards, to look at images in the Filmstrip.
e. I have no idea of everything I could do with ViewNx2, there is a *Lot* more.
I am not suggesting that you do what I do here, this is just an explanation of what I do. There are lots of methods...I guess it is what you are used to. I am not a Pro, never will be, and just a hobbyist, at best. I am comfortable with what I do. I usually do not have over 200 images at a time to upload, unlike some that have hundreds and hundreds or more.
