If you compare water jet vs toilet paper I would argue that the water always wins:
Toiletpaper is a mechanical cleaning method and removing bacterial (aka clean bum) is not super effective with just mechanical force.
On the other hand you have water, a solvent wash, this traditionally has a higher sucsess rate against bacteria. Higer pressure also introduces force.
Additionally the surface your are trying to clean is not flat and contains nooks and crannies, and in this case liquids have a much higer penetration rate than any mechanical force.
However, the absolute best way of bum cleaning is of course by combining them as you often do in the shower, to bad time and location dosent always allow for this.
