Tetris vs. Dr. Mario

I’ve recently been on a huge Dr. Mario kick. Well, actually Dr. Wario from WarioWare Inc, but it’s all the same. This game is so well done and very addictive. It’s gaming in it’s simplest form. I’m left wondering if it is even better than the beloved Tetris… That may be gaming blasphemy, but I’d be interested in hearing which one you like better and why. Tetris? Or Dr. Mario?
