We have acquired several Bibles; we have a 1985 Jerusalem Bible -- a 1973 New International Holy Bible, two Catholic Bibles, a King James version Bible, and an "Authorized King James Bible. -- I have only read the Catholic Bible and have no idea what the others are and one day perhaps I'll compare them all to one another. 
I can recommend
e-Sword ... An electronic Bible platform that is mostly free, with many Bibles, commentaries, dictionaries and the like... For research, multiple bibles are a must... It is probably considered an evangelical (protestant) software, but I know it carries the Douhay-Reims, which most Catholics are comfortable with... I know because I used it for quite a while.
I am KJV-centric... Mostly because it is so well known, and beat up upon... The mistakes within are well defined, and the surrounding references that tie to it (Strong's, Youngs, etc) are hard to beat.
So I stay pretty much in KJV ASV, and ISV anymore... But if you want to knock your socks off, do prophecy from the Septuagint proper... the variation from standard translation (Catholic or Protestant or Judaism) is profound. Likewise the Peshitta. Those two are where you will find different ways to look at interpretation.
