What are the differences between polyurethane oil-based and water-based finishes?

Polyurethane oil-based finishes are more durable and provide a warm, amber tone to the wood, while water-based finishes dry faster, have less odor, and are easier to clean up. Oil-based finishes may require more time to dry and have a stronger odor, but they offer better protection against scratches and heat. Water-based finishes are more environmentally friendly and have a clearer finish, but may not be as durable as oil-based finishes.
