Is luxury vinyl plank or hardwood better for a kitchen?

Luxury vinyl plank, in a kitchen specifically. It is waterproof, which matters in the one room where a dishwasher or a supply line will eventually leak, and it handles dropped pans without denting the way softer hardwoods do. Hardwood looks better and can be refinished several times, which vinyl cannot, so it remains the better choice through living areas. Running hardwood everywhere except the kitchen is a compromise people regret; running the same LVP throughout reads as deliberate.
