Asteroids/Comets/Meteors are divided into 3 kinds. Stony(rocky), metallic or a combination of both. Which is more dangerous when it enters earth's atmosphere and hits us and why?

Stones are, or can be, more porous. That would make it easier to burn up in the Earth's atmosphere.
But, then again, if it's big enough.. it really doesn't f***in matter. :D

i think asteroids are more dangerous to us .
when comet comes towards the surface of earth and when it starts entering
the earth it starts melting and when it touches earth surface it is completely destroyed.
but asteroids are very big in size as compared to comet.if they fall on earth.a large part of earth can destroy

You omitted carbonaceous chondrites. Comets are frozen dirty water/ice. It is the mass, speed and angle of impact that is of greater importance than the composition.

Mass and velocity are the critical features. even a large carbon meteorite would do us in.
