With Frostmourne he was completely under the Lich King's influence right up until he put on the Lich King's helmet and the two joined together.
Sylvannas, on the other hand, was consumed with vengeance and would stop at nothing to get revenge on Arthas. She kills anyone she wants, for no reason but revenge. Now that she can't have her revenge since it was Tirion and "others" who killed the Lich King, she just wants to kill, kill, kill, kill, and kill to make her armies bigger. There's no character development there at all. She is nothing more than a pre-Arthas Lich King.
Garrosh, on the other hand, was a whiny emo who learned that he's not his father's son and began to grow up in Northrend, and by Cataclysm had started to take great steps to becoming the Warchief of the Horde. He despises Sylvannas and her psychopathic tendencies, and he punishes his troops when they go too far (as seen in Stonetalon Mountain). His only flaw is he's expanded his armies too far and he can't control them.
