Opinions, please! They have such a different feel, or I think they do; I was nearly named one of them, and would have preferred the other, though my parents never considered it.
So, how do they measure up: age of bearer, prettiness/plainness of name, all other comparisons you can think of? Any other names that you associate with (either of) them? (I always expect a Sandra and a Patricia to be much the same, for instance.)
