I find Vivaldi most customizable, Brave has horible customization, was using Edge for few years after switching from Firefox, but I was scared of each update and their new annoyances and UI changes introduced, meanwhile in Vivaldi update notification gaves me option Skip this version or Remind me later, Microsoft will nag you with distracting icon unless you update.

IE. I mean, Edge.

That’s Chrome, but with Microsoft telemetry. Hardly an upgrade.
