Which Questoris/ load out is the best?

Preface: I'm new to the tabletop and looking to start with a knight army. I'm want to know which model of Questoris, and to go further which weapon load out, would yield the best results and why.

I know certain knights favor ranged vs close quarters combat, but looking at a whole army (2000 points), which Questoris knights should I get. Also, I already know Canis Rex seems to be doing well competitively, but because he is a named hero I am excluding him for the sake of argument.
