Which way round it is in terms of better or worse I cannot recall, but do know that the various editions differ in the amount of biographical information that they contain.
There are similar compilations of the ministers of the Free Kirk, the Episcopal Church, and one or two others, but they don't all contain the same amount of genealogically valuable biographical information.
These include:
History of the Congregations of the United Presbyterian Church from 1733 to 1900 by Rev. Robert Small, published in 2 volumes in 1904 at Edinburgh
Annals of the Free Church of Scotland edited by Rev. William Ewing, published in 2 volumes in 1914 at Edinburgh
The Fasti of the United Free Church of Scotland 1900-1929 edited by John Lamb, published at Edinburgh in 1956
(Note that many of the ministers of the Free Kirk from 1843 will appear in the Established Church Fasti.)
The Reformed Presbyterian Church in Scotland, its congregations, ministers and students by William J. Couper, published at Edinburgh in 1925
History of the Scottish Episcopal Church from the Revolution to the Present Time by John P. Lawson, published at Edinburgh in 1843
