Its sort of a personal gaming preference. I love them both, but I would say Ages. I never played all the way through Seasons, where as, I've beaten Ages a few times. Ages was a difficulty nearing dark souls levels, but the satisfaction of moving to the next room was so fantastic I would dance in public. So the real choice, in my opinion, is; do you want a more casual gaming experience? Or do you want the full classic Zelda feel in all its glory?
