I hardly find Silver Spoon that bad. Sure, she sides with Diamond Tiara a lot, but the things she does are nowhere near as bad as Diamond Tiara or Trixie (I even think Trixie does more bad stuff in her one episode than Silver Spoon does in the entire series). That, and she does break off from Diamond Tiara's opinions at times like when she was the first one applauding to Granny Smith's story.
