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