Depends on the candidate.
If you have a lib arts background, they will pay closer attention to your quant.
If you're an engineer (or have a highly analytical academic background), they'll pay more attention to your verbal.
Quant is a rough proxy for your analytical sklls, whereas your verbal is a rough proxy for your critical thinking skills.
Regardless of who you are though, a balanced score is always better than an unbalanced one. For top schools, shoot for the 80%/80% split.
