I prefer the grid style though I would A-B test that with various people. I know a lot of folks that prefer an interactive map as well. To me, an interactive map is better suited for more story driven games or a game with a clear purpose of direction. In most brick breaker style of games, the primary function is to break all the breaks and achieve the highest score. It feels less story driven to me.
On another note, what does Salam Aidilfitri mean? I noticed it in your signature and I was curious.
