I carry my well-worn NASB thinline to services and it's also the Bible I've taken with me to the pulpit on the occasions I've been given to preach and the Bible I use to lead our Wednesday night studies. I've had it for probably 10 years or so and it's full of highlights, marks, and dog-eared pages. It was by my side in the hospital when my wife was having surgery in the first year of our marriage, at Cleveland Clinic when I stayed overnight for my brother's operation, and it's been in my hands most mornings and evenings for regular use for the better part of the last decade. I think that's why I prefer it so much to others that I have. I'm more familiar with it, even so far as knowing on what part of the page a particular verse is printed on. In the last year, as my wife and I did a cover-to-cover read for 2015, we read from the ESV, which I am slowly becoming more accustomed to. Growing up, the Pastor at my church preached from the KJV and I used that version extensively all the way through High School. In fact, the majority of verses I've committed to memory are in the old King's English and I find myself slipping into that from time to time when teaching. Our current Pastor preaches from the NIV and that was a key factor in which version I bought for my wife on our first Christmas together.
May the Lord grant you peace,
