I can only answer for two of them -
Jehovah’s Witness: Only 144,000 go to “heaven” while the rest of the faithful get to stay on a perfected “garden of Eden” type earth and live there for all eternity.
Mormon: Three levels of afterlife. One is where you go to live with God and become a god yourself. Depending on the mormon sect, you can become a god of your own planet and have children eternally to populate that planet. The second level is like the Jehovah’s Witness heaven for the non-144,000. You live on a perfected earth. I think the last is “outer darkness.” They don’t believe in hell, per se, but outer darkness is where rotten catholics like myself will go if I don’t start following Joseph Smith. No pain, no torment, just darkness. A lot like the old idea of “Limbo.”
I personally will never be either of the two faiths above because their idea of heaven sounds like hell to me. I just want to by with Christ forever and worship at his feet. I do NOT want equality with God, I do NOT want “eternal life” to explore the earth, I simply ask Christ that I can be in his presence and worship him forever. That would be heaven to me.
