A friend and i were leisurely discussing the use and deployment of batons within the line of duty

. He believed that batons are rarely used by officers as C.S is more favourable in self defence than striking (he presumed ). However i believe strictly talking self defence, i.e restraining a person an officer wouldn't hesitate to draw his baton if he felt it was necessary.
I would love it if you anyone would could settle this debate, by firstly giving there personal experiences of using a baton, strictly in terms of restraint and/or self defence. Then Secondly stating which item there more inclined to use say if both were required, basically which one would you choose?
Many Thanks in anticipation!
