I’ve never found them to be more performant, and i can’t understand the logic of why a programme running inside another programme would be more performant except in comparison to unoptimised alternatives.

I’ve never used a web app that i thought was better than a local app. But i definitely understand why developers prefer them.

It’s definitely been the direction of travel for the last several years. Not because the products are better, but because it’s easier to develop for just the browser than for Mac, Windows, and Linux.
