Yes, as Herb said if you are recording multiple inputs at a time it's good but if it's just you then you don't need a multichannel.
But with the Behringer UFX you can record to separate wav files for each input as well as the master to a stereo wav, you can also record them pre FX so they are dry for adding FX in the DAW.

EDIT: To record a guitarist direct input, you can input direct from the guitar then plug a lead just into the first "click" of the send socket then out to his pedal or use a di box and record with both di and fx (how RealTracks are done).
