"Real" Kirsch is a cherry brandy, in classic form actually distilled from cherries, and depending upon the brand, some sugar. "Cherry Brandy" (in much of the US especially) is more aptly classified as a "liqueur" which, while perhaps produced from a "brandy" (no-cherry in base distilling), is simply distilled alcohol, cherry "flavoring' (if you're lucky, all from an infusion of real cherries), and sugars.
