It's a bit of a circular argument: "I'm invested into using X therefore X is a good choice". This tells us nothing about the quality of X, although I'm sure it means the world to you personally.

That's why I said _for me_.

I've no idea how good Xamarin is at doing the things that it does, but even if I hadn't invested X into my web-based components Xamarin would still force me to reimplement them again in case I need them in my website. That's not cross-platform enough for me, Electron in better in this regard.

Why the downvote?

Pay no attention to the spurious "background cosmic radiation" downvotes, it averages out over time anyway.
