1. The latter are not distributed, like transmission line
2. The former can use stubs and quarter-wave transformers, unlike the latter
3. Transmission lines use the principal mode of propagation, and therefore do not suffer from low-frequency cutoff
4. Terms such as impedance matching and standing-wave ratio cannot be applied to waveguides
Transmission lines use the principal mode of propagation, and therefore do not suffer from low-frequency cutoff
