The TC Electronic VSS3 reverb is great. It has numerous presets for post, and it's the same algorithm as found in the System 6000, so it's easy to match a reverb commonly found on dub stages. Great sounding early reflections and very useful for smaller stuff.
Altiverb is excellent for post, they've changed their UI in version 7 so you may find it easier to use now. They've also added an algorithmic reverb to the plugin which helps add brightness to darker IRs. Plus I dig supporting them because their customer service is so great, they're a small company, and they continue to supply awesome IRs to their customers (where else can you find IRs of the Great Pyramid of Giza or the Cistern in Fort Worden). It can be a DSP hog though, so I often find myself printing reverb returns with it before mixing.
Echoboy by Soundtoys is great for weirder stuff. Plus, sometimes a little delay is all you need.
I haven't tried but I am interested in checking out:
IRCAM Verb, everything by Valhalla, Eventide 2016 Reverb and Blackhole, and the Lexicon PCM Bundle
