As far as I know, the Gospels are the same, both Protestant and Catholic, with the exception of a very few disputed verses. Luther kicked out the Epistle of James, because it speaks of good works, but that’s another matter.
There are, of course, different translations, but that’s mostly a problem with the modern versions. I’m Catholic, but I usually prefer to quote the King James Version, which was the standard in English for centuries. The Revised Standard Version, based on the KJV, is also good, but was replaced by the New Revised Standard Version, which was spoiled by political correctness.
I wasn't speaking of "translations" or even the "books" of scripture we know of as "the Gospels" but the
Gospel itself, the good news as it were, when I spoke of
the information at the two links which I pointed at as being significantly different "Gospel" than was originally preached by the Apostles, and it could be added, spoken of by Christ himself.
I even provided some brief example of what "different" Gospel was preached, for it was not the gospel of Christ, as preached by the Apostles (and the first couple or few generations of successors to those persons) but something different. The synthesis which is Marianism, is not the Gospel, but more like some strange, pious sounding distortion of "gospel".
I provided links previous, here again is one of those links, taking one directly to the portion I find in conflict with the original "Gospel" --->http://www.ewtn.com/library/montfort/truedevo.htm#Supplement
Anyone who tells me that sort of thing is Gospel, is either confused as to what the Gospel is, or is a Roman Catholic Marian devotee (but I repeat myself).
Still, there are those in the [Roman] Catholic church who don't go quite far as the syncretism double-talk of Montfort in their own "Marian" devfotions, as does Montfort's own imitations of Bernard of Clairvaux devotions, whom the RC church has declared both, to be a saints.
As far as I know, the Gospels are the same, both Protestant and Catholic, with the exception of a very few disputed verses. Luther kicked out the Epistle of James, because it speaks of good works, but that’s another matter. I don't think there are disputed verses. You may have some modern versions that use brackets on some verses and foot note it as "does not appear in the earliest manuscripts." But it will be hard to find a Prot theologian to say "ignore those verses."
Luther did not toss James. It is in all the Prot Bibles too. He did have issues with it, but "upon further review" he saw the authority of James not to mention the richness of it. James does not contradict Paul's epistles. In fact James is a great compliment to the other epistles. James rightly said if you do not show the fruits of salvation then your faith is dead. Jesus, Paul, Peter, John all said the same thing. A good tree does not produce bad fruit. If the root is good, the fruit will be good. Calvin had a lot to say about that too.
