As to fuel efficiency in the 986, I checked the brochures that I have at home for the 1999 2.5 and the 2000 2.7 and 3.2 and nowhere is improved fuel efficiency mentioned, whereas the improved performance is. I agree that high-reving 'peaky' engines should be geared so as to have their engines typically running at higher revs; however, the 2.7 was actually less peaky than the 2.5 - i.e., the torque curve was more flat in the sense that it had a greater percentage of peak torque available down low in the rev range than the 2.5. Of course, this is exactly what you would expect with the increase in stroke in the 2.7 over the 2.5. This is all part of matching the engine to the gear ratios and, while I have no doubt that the gear ratios in the 2.5 are ideal for that engine, I also believe that the same is true for the 2.7 and 3.2 engines.
The higher rev limit does contribute to higher speeds in each gear - increases that are greater than one would expect from gear ratios alone. As I have already said, that is a real boon in the cut and thrust of driving around town as well as for autocross, where one need not shift out of second gear (unless the maximum speed on the course exceeds 65 MPH, which is pretty rare in my experience).

The 987 certainly has more torque at lower RPM, feels like what the 986 S feels like, which is probably why many people say a 987 feels like a 986 S
2nd gear lasts just a little longer in the 987 than 986. 986 red-lined around 63mph, 987 is closer to 68mph. 3rd is a huge difference, 986 red-lined at ~92mph while 987 red-lines closer to ~105mph, approximate because I have never driven those speeds on public roads
