One thing I really hate about electron apps (besides performance in many cases) is the extreme branding they do. Every app looks differently, not fitting in with the rest of OS.
As a user, theming is a powerful feature to make things look somewhat consistent.
Though I use KDE and Qt apps as preference, and very few gnome apps. They tend to cope with this pretty well.
As some who normally uses GNOME, I actually like apps to have distinct visual identities so that they are easy to tell apart at a glance. When using VSCode or Chromium I prefer their native title bars and modal dialogs, which integrate with the rest of their appearance, instead of the grey system-provided widgets.
I can imagine.. But everything about GNOME rubs me the wrong way, so I find it hard to compare. The huuge title bars even when I don't have a touchscreen, everything hidden under a hamburger menu, the lack of configurability..
So for me the comparison against KDE is very different. KDE's tools have pretty sane defaults and can be customised very well.
