I'm a fan of convolution reverbs (plate, halls, you name it) and plugging in some of the Bricasti or Lex IRs and letting the machine do its trick. I really believe the Bricasti IRs are outstanding, and many of you are probably privvy to the charades that went on regarding their release (essentially free, though Acustica originally had other ideas.)
I'd like to check out Altiverb specifically for some orchestral projects, but I honestly cannot tell a big difference among the others. Liquid Sonics' & Logic's Space Designer both have good interfaces, good engineering, and most importantly sound good as heck. I'd really like someone to do a blind test on one of them vis a vis the one of the Lex models (there are multiple IRs out there) or the M7. The fella who made the originals did so in a very tenatious, comprehensive manner:
"About 12 years ago I sat down and recorded a complete set of impulse responses from the legendary & industry standard Lexicon 480L digital reverb unit. The reason for doing this was so that I could have a “virtual” Lexicon 480L inside the box in my Pro Tools rig via Audio Ease‘s excellent Altiverb plug-in." --

THey too are availble for Waves & Space Designer. They're quite well done, and Acustica actually took their samples thinking they'd be released commercially. The powers that be agreed to disagree, and a major product was released under the condition there was no charge. Hence we have the M7s.
If you have not checked them out, they're terrific. I feel like I have more direct control with convolution, almost like it's an extension of hardware, and from my perspective the library is huge (Eventide & Other IRs recently have been added too,) and I don't need to know the algorithm is happening inside my computer. If it sounds good, checks in well, and does the job well-- and for me much more easily-- I'm very much sold on the convolution value prop. Many disagree, many, but a good convolution reverb with a great IR can sound as good, or better, than any algo in my opinion.
It's probably not the most poplular opinion, but some agree of course too. Just not the devs.
Here is some press from 2014: Liquid Sonics is mentioned, and Altiverb of course is too:

Given the fact that Space Designer comes with Logic, and Cubase has their own version that I hear is equally as good, it isn't a very popular thing to say or promote on a site that caters to gear heads and engineers, but even up against Liquid Sonics or Waves the same holds. Many know SD used to sell for upwards of $450 USD on its own.
My prediction is the next "wave" of high end reverbs to make a big splash will be massively treakable and massively easy to use concolution reverbs. No one since Altiverb has really offered a major high end product in the mid-range / upper end consumer to pro market. H-Reverb was a twist.
Why make it more difficult than you have to as the jury is out as to which sounds better regardless, and I happen to like the convolution hands down-- with "live" IRs of "real spaces & places" or IRs of analog emulations, as with the Lexicons or Eventides.
As is, for many people, SD can come as close to Altiverb as needed and the cost is minimal, again not a popular subject on Gearslutz.
