This not is a comparative, ist curiosity only.
The programs are almost identical, of course are scheduled for the same person, Michal Rudolf.
Although commercial version with Hiarcs engine is included.
ChessX version is totally free, even with the source code to entangle. http://chessx.sourceforge.net/
Feel free to try ChessX, is a good program and you can add any engine.

P.S. Do you know if chessX has the feature engine vs engine?

From what I heard it keeps databases on file in PGN format (like XBoard does too, at the moment). So it can never be competitive with SCID, which uses a compact and machine-friendly storage format. It is really a pain to parse SAN, as it requires rule knowledge, and in some cases even legality checking. Of course after having loaded and parsed the PGN game, and converted it to an internal format, searching the database can be fast.
I am considering to add an option to XBoard to save the internal format for every large PGN file you load (say > 1000 games), in a file with the same name, but another extension, so that later loads could substitute the compact database for the PGN. Or perhaps only for the moves. So that tags and comments could still be taken from the original PGN, if needed, but searches on position wuld not need processing of the SAN in the PGN.
