I absolutely love how a rangefinder handles.....it's great. But if I can only have one, it's the D3. Instead though, I chose D700 + M2 and CV 35/2.5. I shoot the M2 for pleasure, never on a paid gig though, and the D700 handles all of my paid work and occasionally shooting for fun, because it works with my strobes and the leica is a natural light camera.
