I feel like slack is decent. It definitely feels like a webpage, but the embedded UI elements are good -- the text boxes support all the MacOS shortcuts, you can insert special characters using the character viewer, text selection works properly, the menus aren't weird.

I guess maybe I'm just so used to web stuff now that that codes as "native enough" to me?

interestingly, it looks and feels like an electron web-page. They're all following their own little paradigm now..
