It depends on which kind your talking about ;)

Technically speaking, there is no "best" hockey stick, though there are many good ones. Personally, I would choose Reebok 10k. It also depends on what position you are, and what kind of player you are. Are you a grinder? Sniper? Dangler? These all help determine the attributes of yourself, and what kind of stick you should buy.
Bauer Total One

A hockey stick is a type of lever, which is a simple machine. It allows the user to apply a force at one end to launch or move the puck at the other end.
In a video of her playing using the blue stick, it is an adidas x24 compo 5 stick. I have it and its a very nice stick. Around $220
Alexi kovalev uses the warrior Dolimite spyne for hockey
he uses Bauer TotalOne as of 01/25/11
It is a third class lever.
These kinds of sticks are made of composite and are harder to break than wooden sticks. They are the best kind of stick for an advanced player.
