I think it would be better off as it would avoid the massive economic destruction of Punjab and Bengal and also not have to deal with the Siliguri corridor. But I digress.A whole India isn't necessarily a more powerful or successful India. It's also quite possible that the lack of Partition leads to increased domestic instability and infighting with various insurgencies. A combined India/Pakistan may end up being poorer, less stable, and weaker then what either country ended up being in OTL.
And India that doesn't have to spend tons of money on national defense can use that money for education, healthcare, development etc. It can also invest more resources in diplomatic ventures and present itself as a champion of the third world.
With all this in mind, should a Sino Indian war still happen, India can present this to the world as a great victory of the non aligned movement over the communist bloc.
