Bradley, I myself use Vivaldi, one of the reasons being that it simply never changes. Updates only update the engine, add new features and fix bugs. There haven't been any significant UI redesigns ever since the first stable release.

I don't "expect time to stand still". I just hate this kind of unnecessary churn, and fashion, in general. UIs don't have expiration dates on them. They don't perish if you don't change them every X years. If something works, leave it alone unless your changes are going to result in a noticeable improvement for the user.
