Trixie's my absolute favorite unicorn other than Twilight Sparkle. I think Sethisto had a hand in making me feel that way, but it mostly happened on it's own.



I actually saw Rainbow Dash as best pony before I had some time to watch the show more and develop more favorites. If I was asked why, I'd have to attribute it to her tomboyish nature, (I think tomboys are adorable)love of flight, cockiness, and those absolutely irresistible voice cracks.



As for Gilda, gryphons were already my favorite mythical creature long before I discovered FiM, so maybe I was a little biased when I first saw Griffon the Brush Off, but that doesn't mean that was the only reason I fell in love with her.



Tl;dr Gilda, Trixie and Dash are awesome, despite having personality quirks that many bronies see as negative.
