interestingly drinkable is mostly used for water that is NOT drinkable:
no  1614  68.80%
yes  689  29.37%

while drinking_water is mostly used for drinking water:
yes  296  44.85%
no  230    34.85%
Yes 78    11.82%

so if the question would be "which tag is used to indicate water
suitable for drinking" it would be not even double the use for
drinkable compared to drinking_water.

All of those are still not very much in absolute numbers (e.g. there
are almost 30000 fountains in OSM and 3.5 M natural=water), so I think
we should choose the better and try to uniform wiki and editor
presets. Or decide that drinkable is not the same as drinking_water
(but then the "drinkable" key would at least merit its own wiki page
instead of being hidden on the fountains page).

IMHO they are not exactly the same but so close that they are probably
interchangeable most of the currently tagged objects.
