For me classifying the favorite also involves the experience, because my three "favorite" golf courses were all ones that I played with my father, this is probably not a coincendence, because playing them with him just enhanced the experience even more. The best courses I have played are the ones that I remember the most about in terms of design, architecture, and flow of the course, days, weeks, and years after I have played them. So favorites would be Dornoch, County Down, Cypress. Best would be NGLA, Fishers, San Fran.
