I don't know that I could nail it down to a single favorite... I think the "most playthroughs" award would go to Chrono Trigger, but I actually thought Final Fantasy 6 was a deeper RPG in that generation... speaking of deep RPGs on 16-bit consoles, Phantasy Star 4 completely blew my mind when I played it for the first time. Moving away from consoles, Baldur's Gate 1&2 and Icewind Dale 1&2 took D&D and put it into a single-player experience with all of the number crunching done for me... Fallout 1&2 redefined how I look at post-apocalyptic fiction and got me into all sorts of things I dismissed as crap before... and Knights of the Old Republic 1&2 resurrected Star Wars for me after the dismal disappointment of Episode 1.
so... Favorite? Umm... all of those and more.
