I like the new design better. As a race of bird-people, their designs in BotW more closely resemble that. Also, Rito Village in BotW is really, really cool and suits them better than living in a bunch of caves. They feel like they have more of their own identity in BotW, they seem like they're now more than just the race that evolved from the Zoras. Though I do wonder what happened to Valoo over the years.
