It’s a different version, or different translation, if you will.
It is described as having questions and answers to common Catholic questions about the Catholic faith.
I think your choice of a Bible should be based on what you may find more easier and more comfortable to read for you.
When I have bought a Bible, I have looked at it in person so that I could look through it to read it to see if I was comfortable with the translation to see if I could understand it.
We have a Catholic bookstore in my area, so I was able to do this. I don’t know if you have a store in your area where you can do this, though. I realize that not everyone does.
I am personally more comfortable with more modern translations of the Bible. That is just me, personally.
I think that the more formal translations like the Douay-Rheims are very beautiful, but I personally like a Bible that is easier for me to understand, so I have a few different Bibles on hand at home.
I am editing my post to add that I was also given what was called a “Catholic Study Bible” as a gift. It comes with permanent notes already printed in it, and it also comes with maps in it, too. It’s a great Bible, and I always found it to be really helpful. It explains Biblical history, and translations, too. You might also find a Bible like this helpful, too.
