I don't think there's much point comparing Bruno and Nuno for a good while anyway.
Nuno had a relatively long time here to build something, which was very successful, and we're all aware of his achievements and also his blind spots. It's easy to nitpick about the latter now he's gone, but the former has significantly more weight.
He's still the best manager most of us have ever seen, and as he kept us up as a genuine decent force in the way no one has for most of our supporting lives, Bruno can't really directly challenge/emulate/eclipse him realistically.
What Bruno does have, imo, is a different kind of mission, which is to keep us up as a decent PL team but do it with more obvious style and entertainment. If he can do that it, it might be the manager after him who benefits the most. All this depends in some part on the scale of Fosun investment too
