If you try to compare the two in practice I think you’ll notice a huge difference.
My experience is that in general arguing with people pushes me to articulate my positions in compelling ways. If I want to clarify my thinking, which is something altogether different, other techniques work better for me.
But, sure, I agree that arguing with articulate intelligent people who disagree with me pushes me harder to articulate my positions in compelling ways than arguing with people who lack those traits.
