Poll on Surveys: Open Text Fields or Buttons?

I hear two schools of thoughts regarding the use of automated surveys: some prefer open text fields, others prefer buttons.
Assume you were asked to take a customer survey for a product you use or are considering using.  The survey is short (fewer than 10 questions) and completely voluntary.

(For those that prefer text fields, my apologies.) Please let me know why you prefer one over the other in comments.
