I agree and disagree. If you play surf swamp blues or that type of genre the big Fender valve units are king and do the job in a way digital reverbs can't. But then part of the effect is not the reverberation per se but the low fi nature of the unit - when you hit is makes a spring boing, or dig in and it drips in a certain way. Digital can do that, but it always sounds wrong.
However, that is pretty genre specific and for 'clean' reverb, or more subtle effects or more realistic reverbs that match real rooms/halls/shower cabinets etc, a digital reverb is the way to go - the Hardwire is excellent in that regard.
If I had the cash I would by a Fender 63 Reverb reissue in a flash. However, I have better uses for £600, a Brown Vibroverb with a valve powered spring reverb and so for now the Boss FRV1 pedal or the Digitech will do for my non-reverb loaded amps.
