Bane reduces a drexl and its riders into ash with lightning:
Bane didn't take the time to revel in the fear of his fallen enemies. Before they even hit the ground he'd turned his attention to the third opponent, unleashing a storm of Sith lightning that reduced the riders to ash and the drexl into a hunk of charred and smoking flesh that dropped from the sky.
What has Krayt done in comparison?
Bane is so fast he looks to wield dozens of sabers:
She fell into a defensive posture as she so often had during their training sessions. But this was no drill, and her Master came at her with a speed and ferocity she had never faced before. Giving in to his orbalisk-fueled bloodrage, he was like a wild animal, raining savage blows down on her from all angles, the strikes coming so fast it seemed as if he wielded a dozen blades at the same time. Zannah fell into a full retreat, desperately giving ground beneath the overwhelming assault.
What has Krayt done in comparison?
Bane disintegrates dozens of technobeasts:
Bane thrust out with the Force, and a dozen of the oncoming creatures exploded into dust and tiny flecks of small, twisted metal.
Bane disintegrates two more technobeasts:
That enemy vanquished, he used the Force to disintegrate two more advancing technobeasts, then felt something bump against his foot.
What has Krayt done in comparison?
Bane's orbalisks allows him to be pure offense:
Had the Jedi enjoyed the same advantages Bane's orbalisk armor provided, their encounter would have ended long ago. Bane could shrug off otherwise lethal blows, forgoing all sense of personal safety in a reckless assault of pure offense to overwhelm her defenses.
What has Krayt in comparison?
It's hard to back up specifically because Krayt was far and away the most dominant figure in his era and his only loss goes to Cade "I suddenly have awesome abilities because I'm either Neo or a Skywalker" Skywalker. His overall force abilities seem to surpass Bane's, although Bane's force abilities are more combat specific. What he DOES have is what might give him a win in both saber and force abilities and that's illusions. I don't think Bane has faced anyone of Krayt's character in his era and his saber feats hyperbole notwithstanding (although very impressive would probably defeat Krayt), you haven't listed any feats that would be relevant against a powerful force user in a force battle.
Krayt himself didn't show much with illusions and Bane was able to resist Zannahs illusion in DoE so he'll probably resist Krayts. Bane did have Naga "create entire illusionary armies' Sadows holocron after all.
Banes TK and Lightning are more devastating than Krayts and he can overcome him in a Force battle. Furthermore thanks to his orbalisks he's protected from Krayt getting a hand on him for that technique of his.
