[Star Wars] Is Dash Rendar the most important/greatest non-jedi hero in galactic history?

Let's look at his resume:

* He took down 3 AT-ATs at Hoth, while Luke Skywalker (the only other known pilot to do so) only took down one.  
* Destroyed an entire squadron of TIE fighters singlehandedly
* Defeated IG-88 and Boba Fett in 1 v 1 combat
* Singlehandedly infiltrated the imperial base at Gall
* Destroyed a swoop gang sent by Jabba the Hutt to kill Luke Skywalker
* Infiltrated the Imperial Freighter Suprosa and captured plans for the second Death Star
* Killed Prince Xizor, *"who was considered one of the most influential beings in the galaxy, on a par with Emperor Palpatine and Darth Vader, due to his exceptional wealth and influence through his criminal activities."*

Now, I don't know much about the EU, but that seems like a pretty sweet resume to me.  Who else has as distinguished of a career?

The most important and greatest non-jedi hero in galactic history was the republic secret agent and spy, Manny Bothans.  He was responsible for stealing the death star plans, after all.  But for the courage and bravery of Manny Bothans, the Republic would have been doomed.
