Nope, when talking about “the debate episode” of The West Wing,Iwill always, ALWAYS talk about the Season 7’s episode with Alan Alda and Jimmy Smits (and, btw, the making of in the DVD extras is pure joy to watch!), but you’re absolutely right about the cutting the tie moment as being one of the best.
I’d also add to your list the “it doesn’t go away” moment with Charlie and Josh in the the end of the pilot. And there’s also another reference inalater episode, can’t remember which one.
That said, thank you Sir for putting up this list: it’sapublic service long awaited for.
