Experienced force user Vader pulls a lightsaber on Bib, when a novice like Luke just mind tricks him. What's wrong with this picture?
Vader can actually do something with his saber and can threaten to bring in Star Destroyers, TIE Fighters, and Stormtroopers. Luke isn't as good as using his saber and doesn't have anything to threaten Bib and Jabba with.
