I use The Old Reader since I don't want to be stuck with one browser.
But vivaldi's user interface feels very slow and much slower and heavier than all the other browsers. I tried multiple times. I just can't get used to it.

All of that on 4GHz Haswell.
Vivaldi is Gmail levels slow, new Youtube levels slow. Remember kids, dont do UI in javascript.
Mozilla's short-term vision in not offering an easy to use standalone Gecko rendering engine (to prevent others from making competing browsers using Gecko) is a major factor on why Chrome and Chromium browsers rules the roost today. And Firefox keeps losing its market share. It's a good example of greed corrupting open source philosophy. (They seem to have shortsightedly realised this for mobile platforms with GeckoView).
In choosing Chromium / Blink Vivaldi has chosen to sacrifice all the philosophy of the old Opera browser - creating an innovative, blazing fast browser without being a resource hog.
We need more Webkit and Gecko based browsers.
