In an argumentative essay, strong disagreement is often signaled by phrases that indicate contrast or opposition to a previously stated idea. The phrase "On the contrary" serves this purpose effectively. It clearly suggests that the speaker is about to present an argument or viewpoint that directly opposes or challenges what has just been stated. This phrase creates a clear and forceful distinction between differing perspectives, which is integral in developing an argument and showcasing disagreement.

The other signal words do not convey the same level of opposition. "Support your opinion" encourages agreement and affirms a stance rather than presenting a disagreement. "Similarly" suggests a connection or agreement between ideas by indicating that what comes next parallels or aligns with a previous point. "Firstly" introduces a point or structure to an argument but does not imply disagreement; instead, it typically serves as an organizational tool to present a sequence of ideas or claims.
