It is neither more nor less accurate; it is merely a different kind of search.
You will notice that, when using the Solve for Mate search, the depth is
displayed as X/X, instead of X/Y. Basically, for the Solve for Mate search, no
extensions are used. This is why, typically, the standard search is faster at
finding mates.
