The Hiarcs Tournament Book is stronger. It combines the best of games from GMs,Computer Play, & strong correspondence games. It is an annual subscription service which updates the book quarterly. There are very strong titled players who rely upon this service in their study and preparation. The Fritz Powerbook consists of only games from strong humans.
The Fritz Powerbook 2022 contains 25 millions opening positions, derived from 1,7 million high class tournament games. Hiarcs15dBook (April 2022) contains 32'736'668 positions and 2'002'736 variations. In my opinion they are very similar. Both are based on high quality human games. Both Hiarcs and Chessbase have other books, stronger ones, that are based only on GM games. And if you want a book to make the engine work easier, then you need an opening book based on engine games. Such books are very strong, but not suitable for practicing chess openings.

For what it is worth GM Larry Kaufman has expressed his opinion that the Hirarcs Power Book is superior to the Chessbase product for people to whom such a product is of importance.
@Ekrabin, these books are based on the same games. Therefore, there are no big differences. Hiarcs book contains slightly more positions, but this does not mean that those additional positions are very strong.

The Hiarcs powerbook is a Combination of strong human games, computer games, and correspondence games according to GM Kaufman in his review of the product. He wrote the resulting tree info is not the same as featured in the Chessbase Powerbook. I am quoting Kaufman, who is besides a GM an authority on computer chess and opening books. Also examine the HanSchut blog for Hiarcs Pro wherein he discusses the superiority of the Hiarcs Books. The blog is available for review here at chess.com
Best is to use a data base.
The books contain information up to a release date.
Games are being played after that.

Not true with respect to the Hiarcs book. It is updated as a subscription service quarterly. If you go in chess.com to the blog by Hanshut he details this. My comments are based upon what I have read from Kaufman and Schut. And truthfully the importance of a powerbook in general is in relation to the strength of the player. Below say 2000 honestly it doesn't matter a lot imo.

Does anyone know: Can I add the Stockfish engine to HIARCS Chess Explorer Pro (v.1.1.2) running on an iMac (macOS Monterey 12.6)? Thank you.
Hi,
Which do you think is best? HIARCS or Powerbook?
Thanks
