If implemented well you wouldn't notice it as a customer (just as you don't notice nor should care much whether your computer has an ARM or x86 CPU), so it's hard to say whether it offers anything over other solutions (unless you care about details like whether a program runs as native code or via a VM like JVM, .NET or WASM) - typically one will only notice the bad apples which then may turn into memes (like "all Electron programs are a bloated resource hungry mess, while all native applications are automatically an efficient marvel of software engineering").
