SWL
These individuals do not fight Jedi and/or Sith in direct manner, they rely on impressive gadgets and firepower to contend with Force-user opponents.I personally believe that even a buffed-up and heavily armed individual shouldn't pose a threat to a well-trained Force-user, not a Sith Lord at least, but this is Star Wars and logic is not its strong forte.
So we are left to hold Carth in the same regard as we do with Jango and other incredibly competent combatants amongst the normal folk.

You think that these are impressive? Explore Grand Champion of SWTOR for a change. This guy pulled off shit that many Jedi won't. Heck, he might even take Count Dooku, and I am not kidding.
This was goofy. The rest is sound, if not absolute. As long as you apply the same standard with both parties (Bane and Malak), you might have a good case here.
I'll leave the rest to Dmb, Neph, or Neb. It'll be interesting to watch. You've piqued my interest.
