Brock and Cilan have some similarities. They are both gym leaders of the first gym in their region who eventually travel with Ash hoping to reach new heights in their dreams. They're both cooks and seems to be the group navigator. The only major difference is that Cilan doesn't flirt like Brock does with almost every female he meets. However, some girls actually take an interest in Cilan and his brothers, Chili and Cress, as seen in Triple Leaders, Team Threats and Dreams by the Yard Full! when the girls in the restaurant stare at them dreamily and cheer them on during Ash's gym battle.
