What are the differences between oil-based polyurethane and water-based polyurethane when it comes to finishing wood surfaces?

Oil-based polyurethane and water-based polyurethane are both types of finishes used on wood surfaces, but they have some key differences. Oil-based polyurethane tends to give a warmer, amber tone to the wood and requires longer drying times between coats. It also has a stronger odor and can be more difficult to clean up. On the other hand, water-based polyurethane dries faster, has a clearer finish that does not yellow over time, and has a lower odor. It is also easier to clean up with water.
