With the minimal amount of evidence we have, it's difficult to say IF the Guardian will return for the last season regardless of Q/As and all that.

In addition its hard to measure the Guardian against Aku based both on what we know on both of them.

We do know that despite his abilities, Aku's powers are not absolute as he was unable to defeat the Goddess of Water and the 3 Elementals. In addition it is heavily implied that he is outclassed by the deities Ra, Vishnu and Odin who had destroyed the original massive evil entity Aku was born from.

As for the Guardian, he himself has said:

"For countless eons I have guarded this magical power of time travel. *All* have been denied, from the mightiest of giants, to the tiniest of warriors."

This implies that he likely more powerful than most people realize as we only saw him defeat Jack, an average sized human with nothing more than his own martial skills and physical abilities. Considering his claim that he has lived for 'countless eons' we can theorize that the Guardian may not even be a mortal creature at all. (Some theories are that he was placed there by the three deities in the first place)

Plus the time portal itself is shown to sentient when it tells the Guardian to spare Jack and it's unknown if it has any other powers beyond time travel.

So it's unknown if Aku can both find the time portal (if he's aware of it and the prophecy) and defeat the Guardian.
