Sturmfels or Sethian?

<p>I'm an intended math major and I want to take either math 53 or 55 this spring. The prof for 53 is Sethian, and the prof for 55 is Sturmfels. </p>

<p>If anyone has knowledge from experience, who would you suggest I take based on the quality of the professor? </p>

<p>Thanks very much for the help.</p>
