The neutrino and the antineutrino are antiparticles, they differ in any given property except of mass, lifespan and spin as well as kind and strength of their interactions (in the case of anti-/neutrinos that’s the weak interaction and gravity). Every other property – like electric charge or magnetic momentum – differs by the factor of -1.
Neutrino and antineutrino are a part of the lepton family and the antineutrino has a spin number of 1/2. They are porduced when a neutron decays, releasing a proton, electron and an antineutrino. If are familiar with the particle and anti-particle relationship, neutrinos and anti-neutrinos are basically particle and anti-particle pairs and when they interact with each other, they annihilate each other.
Neutrinos have an almost total lack of interaction with baryonic matter and very minimal interaction with gravity and electromagnetism (and no interaction with the weak and strong forces). During their travels, they spontaneously change into their various “flavors” or types and back again! This leads me to believe that neutrinos can be their own antiparticle. There is a property of physical objects called “chirality”, which is a fancy way of describing the difference between your left hand and your right hand: the same, but different. In the strange and counterintuitive world of quantum mechanics, the orientation of the observer and the observed have a definite effect on the outcome of the observed process, the collapse of the probability wave function as the physics brainiacs like to say. So, my answer is, there is no difference: the neutrino is its own antiparticle. That is all.
