What mannerisms and praise are different exactly? If anything, he says it in a different tone, as if he reiterates the kind of hype he gave Nagato, in a more respectful manner to Itachi.

Your first example clearly points to the amount of power, Itachi build up throughout his career. Why'd he envy someone else if not for power and for ideology? Especially when all he cared for was power and power only? He bluntly voices his opinion on how he doesn't wanna hear Itachi's lectures but rather want the power he possesses.

It was never hinted that he praised Itachi because he made himself without requiring outside power. He blatantly makes a broad statement in reference to all of his Edo Tensei, and calls him the best.
