It is also dependent on your timeframe and trading setup depending if you want to use a PnF Footprint or Timebased Footprint and also what setting for the reversal for the PnF depending on the market.
I find CL is good for a 10 tick reversal PnF compared to something like the ZB where you would only have around a 4 tick reversal PnF.
Since the PnF is rotational it shows initiative auctioning alot better so it is good to use on breakouts, opening drives & swing trading as it doesn't show every little pull back that might happen in that time....So also good for one time framing etc.

The Market Delta YouTube channel has some videos on this and can probably explain it better than me.
