IMO, the biggest death so far, was Kobe Bryant. But because it happened before Corona, it feels weirdly long ago. That death dominated for 2-3 days.
Ghislaine Maxwell also has big death potential. If it happens, there will be conspiracy theories for years (again).
In terms of biggest names... I don't know. Yes, we might not have had the A+ names, but we certainly had A-names, and quite a few at that, especially on the death list, but also Ennio Morricone and John Lewis and Kobe.
