So kicking Aayla Secura and clashing blades with Windu for a few seconds is more impressive than his showing against Jinn and Kenobi? I highly doubt it.
And yes, he has more Force feats; bear in mind we're comparing him to the guy who not only still has his legs, but was capable of bringing a building down with a Force scream as a teenager, or could move "massive boulders" around without a shred of effort. The real difference is that TCW Maul is more unrestrained.
