There are some minor differences of contents among Bible versions, but except perhaps if you are comparing Gnostic Christians with non-Gnostic ones the four Gospels are safely within the consensus.
There are about a half dozen books that Protestants do not recognize yet Catholics do. Orthodox Christians sometimes recognize the same books that Catholics do, sometimes a few more.
Gnostic Christians are perhaps less likely to make a point of stating which books are canonic, but in any case they value a considerably bigger selection of books that were found more recently.
Generally speaking, the differences in canon are far less significant than the passion of some would lead one to believe. So are the differences of translation. Interpretation is a far, far more thorny challenge.
