grades and extra-curricular activities

Would you go for the person with high grades and no extra curricular activities or the person with a lot of extra curricular and low grades?

both will be considered - person with high grades and no extra curricular; and person with lots of extra curricular but low grades.

high grades and no extra curricular activities to me mean the person might have good intellectual abilities but might need to work on leadership or people skills. in the interview i will probe on leadership and people skills.

low grades and lots of extra curricular activities means the person might have good people and leaderships skills. in the interview i will probe on how responsible or irresponsible the person is. will also probe in intellectual skills and communication skills.
