We really can't judge Sion's saber skills too well. He is likely very good as his ability with the Force and his will is so strong he can reknit his entire body and keep it together. That's very very impressive. But he's also a leader of a sect of Sith dedicated to assassination and attack from the shadows; it's seldom he likely even has to do an honest duel, really. I'm leaning a bit towards Bane in saber ability, but I'm not sure it really matters. The upper limit of Sion's resistance is never stated, and he only ever dies when he is broken of hope; never is he torn apart or otherwise destroyed. It's possible Bane could trap the Sith Lord, or perhaps shoot him into space, but it wouldn't be a straight duel in that sense.

That is a possibility. Unfortunately no background material covers his ability in depth, and it's never done in-game so it's hard to tell. We can't even really see the effects of the damage done by the Exile's saber in the cutscenes, though we know that Sion's body is literally shattered and crushed all throughout and that he's keeping it together through force of will.
Since the ability makes for a serious assumption on either end, I ride the fence on most of his battles. We simply just don't know enough.

It certainly seems a gameplay mechanic, but the information you find on the Harbinger supports that he does indeed survive amounts of stress and damage that Bane can't really hold a candle to. Lava? You're right, I doubt he can take an Anakin bath and come out looking cute.
Well, in fairness, given Bane's skill, Sion would have to do the damage...Sion can indeed survive a lot to hold himself together, but facing someone like Bane...or to overkill, Luke, Palpatine, Yoda or Kun? His chances ain't too rosy
From what I've assessed, Darth Sion's force capability is heavily underestimated. He had every bone in his body broken (Literally, from what the game proclaims) and he has the ability to hold them together. Perpetually. While moving, Lightsaber training, jumping, crouching, speaking, physically harming Traya and killing Jedi after Jedi.
Off Topic/Off the Record: I'd say the Triumvirate are excessively powerful because of three main attributes each Lord holds:
Darth Traya: The ability of masterful manipulation and being able to kill three Jedi masters within seconds.
Darth Nihilus: The ability to drain a planet of it's energy and draining millions (Arguable) in the process.
Darth Sion: Practically invincible except by means of verbal harm. Strong will of the force by holding body structure intact after severe damage.
To swerve back onto topic, the two both possess powers that make them practically unstoppable.
Nihilus was weakened when trying drain her but couldnt because she was a wound in the force.
Sion's saber skill is still an unknown and she convinced him to die we dont know the exact details of how she did that or how close the duel was actually.
Traya is the only one which we can legitimately say she is stronger than. Yet she holds revan with such high esteem and makes comments like him being the heart of the force. m
And dont underestimate malak he was very powerful. his duel with revan on the star forge was an epic one and he was described as nearly unstoppable.
