Your diagram on the left, is best case scenario for loading for c-channel. Take into consideration the I-section for the channel in both diagrams, The strength in your material is related to your longer leg or the web of the channel. Example: C6"-13# channel Ix-x (related to loading in left diagram) is 17.3in^4 where as Iy-y (related to loading in right diagram) is 1.1in^4 The channel is 15x stronger in the vertical position (left diagram). Keep in mind though the c-channel will still want to twist under load, even in the vertical orientation (left diagram).

precisely, you could calculate the bending moment and the deflection and then decide which configuration is better.
