The trick with verbs in music is .... hmmm ... how should I explain this ?
To put as much on as possible without actually hearing it. Does that make sence ?
Anyhow, the ONLY reverb plugin that even comes remotely close to hardware in that very aspect is the Eventide reverb plug. Convolution stuff is a complete disaster when it comes down to that and there are a couple of plugins out there which are pretty ok for that. Revive and Reverb One for example. I hear good things about the sony's but I haven't tried that one yet so I can't judge.
Now, in the hardware world that's where Lexicon boxes rule. Sound wise there are definately other options like TC and Kurzweil aand Eventide of course.
I mentioned music, because there is definately a difference when you're doing post for example. I can understand the convolution excitement for those people. I do the occasional post thingies and that's when I appreciate them (a little bit at least)
nah ... if you're serious about reverbs you should look at some hardware imho.
