Water is also best used to smother a fire. Taking energy away is much less efficient than taking oxygen away.
Anyway, if you’re frying a lot and grease fires are a worry (bigger than you can smother with a lid), get a class K extinguisher for the kitchen. It turns your oil into soap, and soap doesn’t burn.
Smothering works on more fires than water, go with that.
