My fave reverb to date is the Mr Black Eterna, however thats a Shimmer reverb, at extreme settings it sounds like a choir, beautiful pedal.
That is, understandably, possibly a bit more specialised than you're after, so I would definitely recommend the TC stuff (either the HoF or HoF Mini), they also have their new Trinity 2 out, which has a ton of reverbs on it.
Must give a shout out also to the Marshall Reflector, discontinued now, but probably still the cheapest of the above, sounds great and has a few different reverbs on it.
