It doesn't make much difference, but I thought I would be more specific and say that I use the 1995 update of the NASB, most often. It just took out the "thee's" and "thy's." I'm sure there are some out there that prefer the old version of the NASB. Occasionally I like the old American Standard Version, also.

Grace is but glory begun;
Glory is but grace perfected!
