Which DS game is better: Professor Layton or Mario and Luigi: Partners in Time?

I wanted to get a new DS game for Christmas, so I need to know which game is better: Professor Layton or Mario and Luigi: Partners in Time?





I know it's mainly a matter of opinion, but here are the things I'm looking for.





I'm a pretty good puzzle solver, and the video game needs to be able to last me a long time.





However, I'm currently leaning towards Professor Layton. Can you tell me which one I should get?





Thanks!|||Professor Layton :) no doubt :)|||Professor Layton is worth the money in the end.|||I love Professor Layton, but I've never played the other game....
