I'll start. Mine is probably Utahraptor; It's big size compared to other dromaeosaurids makes it a majestic creature for me, but it's popularity overshadows other cool dinos of the same type, like Dakotaraptor or Austroraptor
It is definitely overrated and innacurately portrayed in media way to often. Search up velociraptor on google and all you see are JP-Style Raptors
They overshadow any others of its kind, especially Deinonychus
All Hadrosaurs and Ornithomimids
Pros
Amazing and diverse animals, some of the greatest ever to exist
Cons
STOP USING THEM AS F*CKING CANON FODDER! AN EDMONTO COULD DEFEND AGAINST A REX! AN ORNITHOMIMID COULD KILL A DROMAEOSAUR! AND A VELOCIRAPTOR COULD NOT TAKE DOWM A HADROSAUR WITH EASE! IT’S BULLSH*T!
