In my experience with Tauri, it's pretty good on Windows, but not so much on other platforms, especially Linux. The decision to target different browser engines on each operating system means you still have to deal with a bunch of different OS-specific bugs.
For Windows you're dealing with Edge (so Chromium), on macOS you have Safari, and on Linux you have WebKitGTK. WebKitGTK has honestly abysmal performance, and you're missing a lot of modern standards.
The Tauri devs are looking at bundling a Chromium browser with it to deal with that, but that's still some time off, and leads to the same issue Electron has, where you have large bloated applications.
