Bun is faster because it implements pretty much everything natively and just exposes them in JS, not because it uses JSCore
I believe long term, V8 will become the undisputed champ again as Google has a lot more incentive than Apple to make the fastest engine, but this is just a wild guess of mine, and I'm biased being a Node.js Collaborator
I've been hearing for a while that JSCore has a more elegant internal architecture than V8, and seeing the V8 team make big architectural changes as we speak seems to support it [1], but like I said, hopefully they will pay off long term
