Not much different but enough to be dangerous. Older Windows use Trident, 10 still uses EdgeHTML, many people are stuck with old Androids that don't have up to date engines (not sure if Android is a target, wasn't easy to find in their website), and webviews have access to the system in ways a website doesn't (like reading files or using the camera without having to ask for permission or being allowed to issue requests to arbitrary domains).
That is not how it works on Windows, as you have to ship either the Webview2 runtime or installer with your app - otherwise you’re stuck with the old rendering engines.
At which point, it’s just easier to ship Electron.
Shipping Electron and bundling the WebView2 runtime are practically the same level of difficulty.
Making an installer is not that hard, and you should have enough respect for your users' compute resources to go through the modicum of effort it takes.
