Gravitational pull is determined mass and distance. The greater the mass, the shorter the distance, the greater the pull.
1. This is what distinguishes neutron star from any other star - distance to the center.
2. Black hole is commonly considered as a singularity, 'pure mass'. So, at the same mass, a black hole would generate the greater pull than a neutron star.
However, an international team of astrophysicists has now found a distinctive signature of black hole event horizons.
3. Neutron stars are among the densest objects in the Universe. Still we can distinguish between a neutron star and a black hole as neutron stars release emissions from the hard-surface.
You need to rethink your question "power" is not the word you want. Likely "strength" is the word you want. And, your question is likely not as simple as you put it, do a bit of reading on Wikipedia about black holes and neutron stars, think about it, and maybe try again??Which one has more gravitational power ?- A Neutron Star or a Black Hole ?
Was that a deliberate mis-spelling???The answer is simple. The heavier one. Neutron stars have masses between 1 and 2 solar masses, and the smallest known black hole has 6 solar masses, but we will probably find a smaller one. Acording to "sience" there are also micro black holes, so...
