according the current situation in bundlers written in JS，there is no "really" winner in my opinion。 webpack or rullup，which one is winner is a very personal thought。
So i think there maybe some similar situation in bundlers written in Rust.
Wepack for web apps, rollup for libraries.
Very much depends on what you're doing, the tools usually aren't good at all of them. There's 1 or 2 other use cases I'm forgetting.
