Well historically I loved the historicals (3039, 4th SW Atlas, Brush Wars, Civil War) the more recent ones seem to be lacking in the detail (at least the turning points).
The era reports are *almost* perfect, the 20 year update was perfect, as it listed all the units for the the factions. The new era reports completely left that out, which *amazed* me when I was reading 3052, I was like "wtf?!?" just expecting it to be in there. If those books had complete units I'd be *much* happier. Well, if the era reports *or* the field manuals.
I am kinda getting sick of TROs, there are so many units now its just insane to keep up with :(
The plot books meh, War of Reaving is a great book, but I have no desire to read that much fluff... I went straight to the new rules, new maps, and unit rosters (only to see most of the clans had no rosters, hopefully those are in the new field manuals).
Give me a single year, give me all the units (preferably with a *bit* more than just quality/morale/strength, maybe a weight class/#fighters/integral DS/JS too) for that year and a good map for that year, in any book, and I'm a very happy camper :)
The HTP books are close to great, but I think they need to detail out the battles more, like the old Galtor book for example, I read all that fluff, it was all combat related, not political, I don't enjoy BT for politics, which leads me back to War of Reaving. Heck, just picking a planet, detailing the exact units landing there, a map of the planet, some maps of where units moved and where battles were, terrain/maps for those battles, and a few pages of text on what happened at each battle would be a great $5-$10 PDF, and the possibilities I would think are infinite.
However I'm different than most players, so feel free to skip right over this :)
