Wooden utensils are best for when you need something that won't conduct heat. Although they can burn if left on an open flame, they are great for stirring and serving. More than anything, they won't heat up to ridiculously hot temperatures, and won't damage cookware. However, wooden utensils have a tendency to crack if you wash them too often in the dishwasher and expose them to heat. Similarly, plastic utensils are best when you need low or no-heat applications. They’re great for tasks such as stirring cookie dough or scraping food off of dishes. This is because they can melt when they come into contact with heat. Therefore, it depends on what you need them for. The best thing to do is figure out the things and processes you use most often in your kitchen, and then decide on which utensils to use.
