I've hosted several dozen US tech executives in Pakistan over the years. Most recently, March '09. Most of them have also traveled to India. Consistently, I've been told that the airports and roads in Pakistan are far better than those in India. I have driven them from Lahore all the way to Bhurban in the mountains, going through Islamabad. We've also travelled from Lahore to Faisalabad by road.
I have not visited India myself so I can only go by the relatively objective views of those who have visited both countries and are neither Indians nor Pakistanis.
Where, for example, is India's M2? Over the past 10 years, Pakistan has added thousands of kms of M2-quality highways (Faisalabad-Lahore, Islamabad-Peshawar, Karachi-Gawadar, Lahore-Multan etc.) While road building happens in both countries, I have not heard any visitor to both India and Pakistan tell me that the roads in India are comparable to those in Pakistan.
Pakistan's teledensity continues to be higher than India's, adoption of clean technologies like CNG is also higher, roads/airports are better... I think it would be fair to say that, on the whole, the infrastructure in Pakistan is superior. I know India is trying to improve too... but then so is Pakistan.
I'm not trying to bash anyone or anything... just sharing the experiences and perspectives of some people.
