While psychologically, it might appear to be the same as any other conversion experience from the fact that one clearly exhibits an entirely new viewpoint, I am not sure that one enlightenment experience is as good as any other.
Hakuin, while reading the Lotus sutra, said that he experienced his greatest enlightenment; that sutra's viewpoint clearly does not in any way comport with fundamentalist Christianity (it could be the subject for a whole bit of comparative religion to relate the Prodigal Son parable in the Lotus sutra versus that in the New Testament).
Moreover, having been raised and believing in Christianity for a good part of my life, I would have to say that the experience of dropping away of body and mind - an ordinary and extraordinary experience - simply doesn't exist in any flavor of Christianity.
And that flavor, on the balance, is more apt to save the ass of all sentient beings than my being assured of forgiveness of sins by a deity.
And there's quite a few pantloads of sentient beings that need saving.
