Round 2 really isn't close. Maul is noticeably faster, more powerful, and a greater duelist by a rather large margin.
He could outduel Cade or dominate him with the force like he did to Kenobi.
He'd lose round 1 too due to inferior dueling ability, Cade isn't in the TK tier to suggest he could overpower Maul either.

Force:
Cade's shuttle feat is in and off itself superior to Maul's own shuttle feat, even without accounting for Cade being vastly pre-prime. Shitting all over Talon who a year prior could KO Sazen with Lightning and Shado with TK > circumstantially ragdolling TCW Kenobi.
And as far as defensive force application go, Cade has: tanking the centre of a lab explosion, shrugging of Muur's mind domination, breaking free of Maladi's and Krayt's mind domination, instantly recovering from Krayt's TK and shrugging of his lightning. These are all superior to anything you could infere on Maul's part, since IIrc his only defensive showing is resisting that Nightsister's Lightning.
Sabers:
Cade as a padawan was fodderizing Nihl's One Sith team on Ossus. Later when he just picked up a lightsaber after 7 years of hiatus he gave a good fight to Nihl, and after his Jedi retraining and Sith training he defeated Nihl in a long bout and straight after gave Vong Krayt (who even that point is at least a Starkiller level force user and more skilled) a long fight where he pushed Krayt so hard that the latter had to go to Stasis.
And this was all a year before his prime. In his prime after fighting through the Sith Temple he fought Reborn Krayt inconclusively for at least a good minute before Krayt resorted to hax.
All-Out:
Combine the above two and add in DT and Shatterpoint for good measure.
