For me, so far it has been BoTW, hands down for my favorite Zelda game of all time, and when it comes to portables I loved ALBW so that was my pick, although Spirit Tracks was a close second if only for nostalgic reasons, I also did very much like Phantom Hourglass and Minish Cap as well, and for some reason Link's awakening just didn't seem to click with me, dunno why, and because of that I haven't played the oracle games yet, infact I've probably got the most unpopular opinion of all time, I love the handheld Zelda games every one else hates, and I dislike the one everyone loves. Oh well Spin-off wise I've only played Four Swords Adventures a couple times, but those couple times were extremely fun so I'll go with that, and while I haven't played the CDI Zelda games, I have watched all 3 of them being beaten to completion, and my favorite of the 3 is The Faces of Evil.
