Since I havent actually played Mirrors Edge my opinion may be a little bit biased. But I have played BG&E and can tell you Ive rarely had a more enjoyable (albeit frustrating at some parts) experience on a third party game relatively few people seem to know about. A genuinely gripping story, stealth sequences if you really feel like it (I didnt once I found the disc launcher), simple yet creative puzzles, auto jumping ala LOZ, flowing combat system if somewhat basic, and my god some truly epic music. So yeah, my votes on Beyond Good & Evil.
