Although these are synonyms (= the act or process of forming syllables, or of dividing words into syllables), prefer “syllabification,” since it corresponds to the more common verb “syllabify” (as opposed to *"syllabicate"). But the two nouns are almost equally common — e.g.: o “Other dictionaries use the same syllabification with a slightly different pronunciation: PLETH-uh-ruh.” Sally Bright, “It’s All in the Syllabification,” Tulsa Trib. & Tulsa World, 16 Feb. 1997, at G5. o “Teachers spend at least four weeks of valuable instructional time teaching children to bubble-in the scantron sheet and to memorize such trivia as syllabication [read ‘syllabification’] rules.” Letter of Deidra W. Frazier, “Let Them Write to Pass Exam,” Advocate (Baton Rouge), 8 Aug. 1996, at B8. *Invariably inferior forms.
