I may be biased because my dad introduced me to old (surf) music when I was a kid, but I love big and almost-clean sounding tube amps specially those with spring reverb tanks.
I am sure people who are good at the technicalities of spring reverb tanks can use them live. I find reverb hard to dial in live, so I don't. Expensive reverb pedals may sound close to a reverb tank, but if I earned much more than I do and had a crew to carry my amp I would have bought a big one with a reverb tank (or an effects loop).
I found this video about a pedal recently, and it is very interesting. It's like a dream for us reverb lovers. Not affiliated with anyone, in any way. Hope you like listening to it.
