Although Tokyo to Shinjuku by Narita Express takes longer than directly by Chuo Line, getting to Shibuya isn't that bad. Narita Express uses underground platforms (basement level 5) in Tokyo and it can easily take 15 minutes from the train to taxi ranks. It probably doesn't make much difference whether you get off at Tokyo or Shibuya.
Well, it doesn't really make sense to me to back track from Shibuya. Also Shibuya's NEX platform is next to New South Exit. If you exit there (easy and not crowded) then there's no official cab rank. Sometimes I see a few cabs line up (blocking the road) there early in the morning, I think (I drive by frequently when taking a back street short cut) but usually not.
The two times I took a cab from NSE then I happened to grab one that was discharging a passenger and the other time I had to walk out to Meiji dori and hail one. This is still a better option that walking through the station, crossing 246.
The cabs at the east exit of Shibuya are heading the wrong direction and maybe can't make a legal right turn up to 246. At the west exit a cab can make an easy left turn onto 246 and head to Roppongi.
I guess Shibuya is a bit closer to Tokyo Midtown.
