The 5 volume set is really histories, and mostly in Japanese with sketch illustrations. I wouldn't buy them for your primary source.
The three volume set came before the two volume set. Both are strictly photographs with some captioning and tables. The three volume set covers:
1) BBs & BCs
2) Cruisers, Corvettes & Sloops
3) CVs, seaplane tenders, sub tenders
These are pretty comprehensive in their coverage. No DDs or Sub volumes were ever published as part of the series.
The two vol set does include those other types by excising some of the material from the initial three types. So, it's kind of a toss-up as to which set is more worthwhile.
The KMM volumes that I wrote of cover all the categories with large format, high quality versions of selected photos from each category. Not as comprehensive, but still very worthwhile.
A little confusing, right? It's actually part of a plot to make you buy all of them, like I ended up doing.
