For cutting dados, an upcut bit is generally better because it efficiently removes chips from the groove, resulting in a cleaner bottom and reducing the risk of burning. However, it may cause more tear-out on the top surface, so using a downcut bit is preferable if a cleaner top edge is essential. Ultimately, the choice depends on whether you prioritize a clean bottom or a clean top edge for your dado.
