Without ever having seen the other manuals, I was leaning towards the Nosler, Hornady, or Sierra.
Though I don't own one, I've been impressed with the Hornady manual.
I do have the Nosler manual, however, and I don't recommend that one if you tend to be looking for a lot of handgun data. There simply isn't much handgun data in it. Not in caliber selection, not in bullet selection, just not at all worth chasing down if your primary concern is handgun data. Lots of good stuff in there for rifle handloading...which makes sense as Nosler's bread & butter is in the arena of rifles.
For handgun data, look at Speer and Lyman's 49th.
