Which is better: a bishop or a knight?

Hi, this is my first blog some please don't expect much from this.

Ok, let get back to the question: Which is better, a bishop or a knight.

now let's see a chart/table:

Piece:                         Bishop                                               Knight

Value:                         3                                                        3

Checkmate:               Yes                                                    No

Pin/fork:                     Pin and fork                                      Fork

Ok, now you saw the chart and you would see that the bishop is better, in my opinion the bishop is better, but some people think the Knight is better. Knights are better in the opening step but in the end if you have 2 knight it is almost impossible to beat your opponent. Well it is not quite possible to beat your opponent with one bishop and a queen but it is possible to beat your opponent if you have a single Knight and a queen.
