I'm not sure if Aku is more powerful than the Guardian. In fact I think it's the other way around. Aku pretty much got his butt handed to him in the first episode (hence him sending Jack through time in the first place) and I don't remember seeing/hearing any implications about him vs Aku in the same episode.

By the time Jack had first met the Guardian he was probably stronger than when he first fought Aku having gone through various challenges in previous episodes yet he still was beaten quite decisively by the Guardian. In comparison Aku has had greater difficulty in facing Jack directly throughout the original series yet only really got the upper hand when he stole Jack's sword.

My guess is Jack will only use the portal once he destroys Aku in future since it's possible that simply going back and slaying Aku in the past will NOT change anything in this present timeline (alternate timelines and all that)
