I'm afraid that's not really accurate. The most massive neutron star observed is just under 2 solar masses, which is difficult to explain if event horizons do not exist. Quark and strange stars are hypothetical objects intermediate in mass between neutron stars and black holes, not suggested replacements for the latter. It is true we don't fully understand neutron stars and we certainly don't understand what happens inside the event horizon.
