I personally have an overlay intro - this cuts off the ~8+ seconds of an intro but is still classified as an intro, I pair it up with my spoken intro and now I have some sort of branding. I like the intros that are sort of part of the channel - like, me personally, when I see the Universal Studios intro before a movie, it hypes me up, it's sort of part of the movie - hard to explain but I hope you get the idea. A text spinning to some music - yeah it looks cool, but it doesn't offer the same feel as say the universal intro
