iPad Pro (12.9 inch) + iPencil + GoodNotes (with zip-file backup) gives me best of two worlds. I scribble my notes with iPencil in GoodNotes. GoodNotes does OCR and its search functionality is good. It allows for backups in a form of zip archives (cloud backup option also available). Unlike Notability (subscription), GoodNotes app is one-time-fee.
