Sharp - agreed, 2 of the best “villain scenes” in the series (one of the other’s being our other finalist as he reveals his plan to Laz up in Piz Gloria).
I think one of the other things that elevates Bardem/Silva/the writing, is that he is one of the few villains in the series where there’s is a real sense of his motivation and why he is who he is. Too many villains across the decades have been villainous because, well, because they’re the villain! From Goldfinger to Kamal Khan, too little time has been spent outlining why they are who they are, other than it appears wanting to be rich. And no, do I don’t expect subtext or backstory in the likes of TSWLM or MR, but other than being “maaaad” why do Stromberg and Drax have a fascination with plain old trashing the place?
The more memorable villains in the series do have more to their character than just their “device” as to plot, and Silva is the best example of a fully fleshed out character with motivations and actions (and words) that reflect that.
