IR-1 and IR-360 are great, TL-Space from TL-Audio too (for ProT**ls only, though), but I think AltiVerb is still leading the pack. For PC, there are cheaper competitors like PristineSpace, or even free ones like SIR (which isn't multi-channel compatible). Hosts like Logic or Sequoia/Samplitude come with their built-in convoluters, as well as the new Kontakt2 or GigaStudio3.
But in the end, it is the quality of impulse-responses that makes or breaks the quality of a sampling reverb. AudioEase has done a lot of first-class IRs for AltiVerb, as well as Angelo Farina for Waves' IR-1/IR-360. There are a few third-party manufacturers, namley Ernest Cholakis from Numerical Sound, and Peter Roos (who isn't recording real rooms, but sampling famous reverb-boxes). - The freeware-IRs on the 'net are low- to medium-quality, with some exceptions.
