Personally, I`d opt for the 35mm lens. Regardless of the sharpness or quality, I find 50mm on DX simply too long.
For most applications, close to a "standard" focal lenght, the 35 seem way more usable. A 50mm lens will be good as a short tele, for portraiture, etc. but not for "general" use.
The longer the lens. the more compressed background, providing maybe a more differentiated subject. Depth of field will be the same on both lenses. Don`t know about bokeh.
