To be honest I can only think of 4 good overtakes by Vettel. Monza 2011 on Alonso, Yeongham 2011 on a subdued Hamilton, Catalunya 2012 (on Rosberg?) and Spa 2012 on Webber. That's rather telling considering how many times we've seen Alonso or Hamilton really go to town when coming through the field, of course part of that is due to his high average qualifying position but even considering that in 96 Grand Prix that is still a really small amount of memorable overtakes.
Vettel is very charming and likeable when he's winning. However should you see him on a weekend like Valencia 2012 he seems very petulant. Yes he's not had the experience of someone like Button or Alonso but he could do with adopting a different mindset, you can't win them all. That to me is his most dislikeable feature (along with what Il_leone stated above, how Vettel expected the team to stop Webber at Silverstone 2011).
