Constant bit rate (CBR) should deliver data in the highest priority as it guarantees a fixed bandwidth for a specific application or service. This is particularly important for delay-sensitive applications such as voice or video, which require a constant flow of data at a steady rate to avoid interruptions or delays. The other categories (ABR, VBR, UBR) do not offer this level of guarantee and may better suit applications with less strict timing requirements.
