There are more than a few good ones.
David Carradine did a remarkable job of playing Bill. It’s a shame he fell victim to his favorite pastime.
Christoph Waltz did a killer job in both Inglourious Basterds and Django Unchained—in the latter his character’s death is one I find genuinely upsetting.
As great as Pulp Fiction is, I think my favorite movie written by Tarantino is one he did not direct: True Romance. That movie features Christian Slater as my favorite lead-character in any Tarantino script, and I also get such a kick out of Brad Pitt as the stoner roommate.
Who stands out to you?
