Sure hydro is a lot more pilotable, or better yet, batteries.
But actually, turning it off 100% is probably the least important property of pilotable plants : you almost never need that. What does matter, however, is that those plants can be engineered to generally follow the daily demand curve and France’s plants can do that at the rate of about 1% per minute.
Also you can vastly reduce the amount of battery capacity needed by having pilotable sources of energy like nuclear, hydro, geothermy and such
Except nuclear is not very pilotable. More than Solar or Wind. But can’t really be turned off either
