Isn't this about performance and not storage?
Making and managing an electron app is easier, but it is possible (with more work) to have clean install/uninstall, a nice UI, and consistent regular updates while still being fast and efficient.
Better programs will always need more work to create.
I am curious about what other options there are, and why Electron is what a lot of people go with.
Answers can be googled but opinions are more subjective?
