Roads in New Delhi vs Karachi
Any way i'll still answer your question
1.Infrastructure
Islamabad wins, because its the best city in this category. search for it.
above link can be a guide.
2. GDP,
Islamabad has only 0.8% of the total population of Pakistan, and even then it contributes an equivalent of
Tajikistan's total GDP to the nation.
3. multinational companies if you means by MNC, there are tons of them operating in Islamabad. there are no statistics available with me now.
Here again ur city wins
4.
Transportation.
A bullet train is underway joining Lahore with this city, and a Lahore's Metro bus system like project is under development.
Both are world class means of transportation. other then that low roof buses operate in the city
I don't know about this who wins here
5. Industries.
Its not a very big industrial city, may be here u win.
Banglore wins
6. Healthcare.
World class health care facilities are available in government and private sectors.
May be same level of healthcare.
7.Educational.
Best Educational institutions are found here in all of Pakistan.
Entertainment and shopping they are in there place.
Though we have got best educational institutions here but Bangalore wins because of more options.
But i am not talking about those things i am talking about the looks of the city.and here Islamabad wins, just watch the above link i posted.
