I prefer Cilan to Brock, however both are repetitive after awhile.
Cilan is at least more amusing for a chunk of time towards the start of Black and White. Brock was only new and shiny for the first season that he was around, and not even that. I think Brock has less to his character than Cilan does, and I also think that Cilan has a better design. He's more interesting to me, especially in the Japanese version where his script is bit more lively, and his voice is Mamoru Miyano, which is a plus. xD
