Ben Skywalker feats and Accolades?

I just read the novel where Ben Skywalker and... Whoever else... (I forgot who else was there) found Obi-Wan's lightsaber, and saw that he didn't really do anything of note, just how powerful is he? I don't expect him to be as powerful as Jacen Solo, (A.K.A. Darth Caedus) but I'd just like to know what he's capable of.

The most powerful thing since luke skywalker

...Bump?

He isn't as powerful as Jacen, but he would've been, imo. He seemed to have the Skywalker learning curve. As for feats, he fought evenly against Gavar Khai, among the most powerful Sith sent to investigate Abeloth, as a teenager.
