Adding to what @pinkandwhite mentioned, that last link doesnt seem to be the most credible even if one just reads the review and ignores the publication’s reputation. Near the top, one of the listed positives is: “Minimalist interface, thanks to the Chromium-based core”.
A few paragraphs into the review:
"Another disadvantage of Vivaldi is its design and approach are not for everyone. Its main search page has way too many options. A huge menu runs on the left sidebar, and the tabs run horizontally on the top.
If you compare it with Chrome’s interface, you’ll notice that the latter is more simple and minimal — only featuring the most important options in the front. It can be a turn-off" 
Oh, and what every browser needs is a built-in crappy free vpn, I guess: “Also, Opera provides a free VPN, whereas Vivaldi and most other browsers do not.”
