Plate reverbs are more than a bit different from room reverbs and hall reverbs, so maybe the argument about algorithmic reverbs being best in algorithmic processors vs. in convolutions, isn't relevant there.
Technically, a plate reverb is an "acoustic" reverb and not an algorithm (real plate reverbs being recorded in chambers with moveable plates, etc.), so it's no surprise that impulse recordings sound much better than a digital reverb algorithmic recreation that may or may not even be in the ballpark. Try PSP EasyVerb, though; they've nailed down a lot of great plate settings.
Again, I think it's all in what you're trying to accomplish. If you're recording an orchestra, real or sampled, especially for a film score, you're going to want a convolution reverb. If you're trying to emulate a real drum room for your sampled kit or a mic'd guitar room for a real mic'd cab sound ... convolution. If you're doing post and trying to either create a realistic room tone for dialogue or using impulses sampled on location to create the same room in post that the location dialogue was recorded in (for ADR and effects), convolution. For most music production, however, I think convolution is overkill.
Considering that convolution didn't really even exist until about ten years ago, and has maybe become a staple in computer audio around five years ago (and is only now widely available due to its inclusion in most DAWs maybe three years ago), the sound of most popular music is still based around digital reverb. I think most convolution sounds real, all right, and definitely high-end and transparent ... but it lacks the character and the flexibility that I've come to know and love from good old digital (or even analog) reverb. I think CSR, ArtsAcoustic, PSP, Breverb and even TC have all nailed decent workhorse digital reverbs that
a) are comparable to most hardware reverb processors,
b) sound great on anything and
c) don't carry the pricetag of Altiverb -- though, as I stated above, convolution is necessary and totally has its place, as well. If all you're doing is rock, pop, rap, R & B, country or electronic, however, Altiverb may be an unnecessary purchase. Just my two unwanted cents!
