Different strokes for different folks! I love Pantheon... it IS lush! I used it VERY successfully on a live session with a clarinetist, and have also used it on vocals, strings, pads, piano, acoustic guitars, and drums. I didn't use it for a very long time, but after I spent a little time tweaking it, I discovered just how rich it can sound.
I think all the reverbs mentioned so far in this post all have a place in our consoles...just depends on the application, instrument, or whatever "sounds good". "Sounds good" is so subjective, isn't it?
