I think its easy to say Ralek because of all the Metamoris bullshit.
I didnt really mind his brothers until after Metamoris 2 when Ryron (IIRC) said in the media that the people criticizing Schaub for #Schaubbing. He said that people were criticizing out of ignorance and that they were "Spectators for a reason". Very insulting, very disrespectful really to all BJJ practicioners and teachers alike.
And I started out at Gracie Torrance for years. Its funny because I know that there are a lot of Rorion and Royce horror stories out there but these two, particularly Rorion, were always extremely pleasant, generous, and accommodating to me in the old days.
