Reverb is like wine, very subject to price, age, make and of course ultimately, taste.
A few thoughts here from a reverb snob (I am also a wine, beer and coffee snob as well
If you are after a great deep space reverb, then you should not look at Eventide, regardless of the preset name on the H7600. Now the H7600 is indeed a great, incredible effects processor, but I don't think you will find many in the pro studio world who would reach for an Eventide unit for just reverbs. They are more known for their pitch shifting, harmonizing and spacial stereo algorythms, but not verbs. I have the Eventide Eclipse which is a great effects unit, but the verbs are pretty bad...
That mantle goes to Lexicon for the most part, and maybe TC if you want realism.
The new player on the block is Bricasti, who only make one product the M7 Reverb which is supposed to be amazing.
Now the snobby part, the reality is if you truly want the luscious verbs you hear on Roach or Rich albums or even what you hear on most music on the radio you are looking at reverbs in the $2000 - $4000 price range. Many will argue but any Lexicon unit below the PCM series or TC unit below the M-3000/4000 series do not even come close to this quality.
The only similarity in the MPX Lexicons or 200/300 series TC units is the brand name.
So what to do if you do not have this kind of cash??? Well there are some decent plug-ins (you will need some decient processing power on your computer) the CSR verbs are nice, Breverb, many Convolution verbs are not bad, as is the reverbs on the TC powercore (they are actually from a TC system 6000), but they are pricey, plus add in the powercore...
...or go used. Yesterday's PCM-70/90 will still blow any modern MPX series away, M-3000's used are in the $700 range...or as JKM mentioned, the Alesis Wedge is not a bad Lexicon substitute if you can live with the noise. I use one all the time live.
Just some opions,
