The Loftwing was a great new way to explore the Overworld. However because the Sky had very little content I found myself only using the bird when I needed to. However the bird was great and just flying around was a cool experience. If I have to pick one though I will pick Epona. It's just so much fun in Twilight Princess to explore Hyrule Field and speed up. And the horse back battles were awesome and made me want a battle on the loftwing (Well unless you count the Levais battle in Skyward Sword) As for what you were saying about art style SS vs. TP. Twilight Princess's art style felt very bland because most if the colors were either black and grey. And even the greens and blue felt just dark. It's not that I don't like dark art styles, but TP made it more bland the dark. Skyward Sword did give a very light art style that was a mix between the Mature look if Twilight Princess and light childish art style of Wind Waker. Together they made a cheery art style that could still look good(At least for me) when your up against a big evil boss. Now I will agree the Twilight Princess was amazing for it's Hyrule and Hyrule Field. These places were huge allowing you to just roam around and have fun and find things like the hidden Goron shop in the corner of Hyrule.
