They’ve got a very tiny bit of rest mass, so the bending is slightly stronger and their pathes differ a tiny bit from the photons’ pathes. And as neutrinos don’t really interact with the matter between the supernova and the galaxy and ourselves, they’ve a much bigger chance to reach us than photons.

(or is the supernova too far away for neutrinos to reach us?)

Makes me wish there was such a thing as a dedicated cluster watching telescope with the sole purpose of imaging as many of these as possible. There are enough galaxies in the clusters and enough star formation going on in the background galaxies that it’s just got to be an amazing sight to see the supernovas light up the fields year after year.
