F 1 Hamilton or Alonso, who is stronger?

I don't think this question is easy to answer. Who is stronger, Hamilton or Alonso? This is actually not very easy to compare. Everyone has his own driving style. In different tracks and different weather conditions, everyone has their own ideas and different driving moods. It's really hard to say who is stronger! Neither of them is weak, but if you have to say who is strong, I personally think Alonso has comprehensive skills and a measured driving. Hamilton is also good, and he has a strong desire to win! However, in F 1, neither of them seems to have a good personality. Although they are both strong, I don't like them very much!
