A 216 is currently slightly (ie, a couple of points) above the mean for Step 1. Traditionally, IM and Anesth are "easier" matches. However, obviously this does vary from program to program - IM at Hopkins is a more difficult match than some surgery programs.
However, with an average score you should be able to match to a fine program as long as you are realistic about applying to a good variety of programs.
A "good" score is usually defined with regard to the field in which you are applying. 216 is a good score for IM but would not likely be seen as a good score for a surgical specialty. Generally, the more competitive specialties require USMLE scores of > 1 SD above the mean.
best of luck.
