I have a number of reverbs I suppose, the few I use the most at the moment...
FabFilter R-Verb
Bootsy's Epic Verb
Nebula with a custom EMT-250 plate library
Others I have that get used less than those... Not that I think these are any worse, I just develop habits and obviously have too many.
Native RC24
Native RC38
Valhalla Room
Valhalla Vintage
Redline Reverb
Voxengo Pristine Space
LiquidSonics Reverberate
PodFarm Reverbs
Nomad LiquidVerb
Nomad BlueVerb
Tal Reverb
TB Reverb
Probably a few more but forgetting without looking. As the others said, decide the space you want it to live in, pick one. About the only thing you really need is being good at using it, how much, does it muddy up and so on, it's all about context.
