I agree with all of these, strangely enough. Though I didn't find Ménard particularly bad as Couthon in LTelV--and certainly not compared to, say, crazy, bunny-stroking!Couthon in Napoléon. Robespierre and Le Bas are especially spot-on in LTelV, though, you're right. And the resemblance of the actors to the characters they are portraying is phenomenal too; Negroni looks a lot like the bust in my icon and Santini especially looks like Le Bas's portrait come to life, in my humble opinion.

And while I agree that LRF had the best Danton and Marat, I don't think I've seen what I would consider the definitive film versions of either of them yet. Especially since Brandauer doesn't really physically resemble Danton much.
