Sidious, as of DE, was far more powerful than his RotJ self. His RotJ self should be a noticeable degree above his RotS version. Given he gradually drained the populace of Byss, all of the time he had to increase his power - and knowledge/artifacts he received from the Jedi Temple.
So, even if we take Mace > Palpatine at face value - we also must accept that DE Sidious is arguably in another league from his RotS counterpart.

Mace is only barely above Obi-Wan in sabers, anyone who says otherwise just does not know the Character.

Mace is only a tier up in sabers, yes but still. Obi-Wan's force powers are laughable in comparison to Windu's, plus Mace will be channeling the darkside so you have two of the most powerful beings dueling and a tier 2/3 duelist with little force power. Also Getting his force wall broken by Maul on the reg is gross.
Plus, Obi-Wan is pretty much Maul's equal and you saw what Sidious did to him in TCW...
Regardless, Maul isn't getting one-shotted.
