id say pakistan, pakistan had so many geopoltiical advantages after independence, a smaller population, more agrarian natural resources, close ties with the usa.
what did they do with all that, lose half the country after the rejection of a democratic vote (this alone is enough to make pakistani politics worse than indian), fight proxy wars which enriched the military and destabilised the socio-economic fabric of the country.
the only positive step pak took was in facilitating china opening up to the usa, which has created goodwill which to some extent has supported pak in recent history. however overall pakistan's political history is characterised by 70 years of mismanagement.
india moved fast to enact land reform which helped stabilise society, whereas pakistan is still stuck in a feudal system of patronage, the "ji hazoor", "ji sir", culture permeates every part of society and results in stifling individual economic and social liberties.
it is not even close in the larger context, Pakistan is one of the most political mismanaged countries in the world. india has its issues but they are far less socially ingrained than pakistan.
i am never for socialism, however pakistan politics is so dominated by the land owning class immediate reforms are needed, and until that is sorted the country will remain politically stifled.
