> In my opinion, the bison parser implements LR analyzer, handwritten parser implements Top-To-Down analyzer. I remember some compiling book says "LR analyzer is better and faster than Top-To-Down analyzer".

IMHO, this phrase doesn't mean that *any* LR analyzer is better and faster than *any* Top-To-Down analyzer.
