NFS Carbon better than Shift??????

Hi everybody I wanna tell you that I played NFS Carbon as well as Shift; their are huge difference between them after playing them both i can say i loved Carbon better than Shift; I appreciate the new features that were embedded in they were awesome but there was a single mistake that it's totally race based theme man; means no police; no traffic etc these things made carbon a wonderful game it had some storyline too but in shift their is only one goal win the championship the main difference was graphic the graphic of both are nearly same but the graphics of shift are of course better than carbon. i love both the game but love carbon better;which one you chose??????????
