If you wish to know which version I personally read from on a daily basis, quite honestly I have about three or four that I read from including the King James, the New American Standard, the New International, and one other one that my mind has went blank on. However, when someone brings up a particular passage I normally look to see how it is in the Greek/Hebrew.
Now if you wish to ask me which Greek/Hebrew versions I prefer, it's the same as Jerome.
Which do you prefer, the Doury-Rhiems or the American Standard Bible? Both are Catholic translations.
Actually I normally use the NAB. We have a table-sized family NAB Bible at home and online I normally use the NAB version available on the USCCB website.
For my Palm Pilot, I normally have a D-R version downloaded from one of the Bible websites.
