Can spacers hurt more then braces?

Neither should: Be very uncomfortable, although some initial discomfort or pressure is to be expected. Everybody has different pain thresholds.

Mild discomfort: Only mild discomfort or sensitivity is expected after the placement of spacers or braces. Medications such as Tylenol (acetaminophen) or Advil usually control this discomfort. You should continue normal brushing and flossing around the spacers and braces. Take care.
