Cons
Con Owned by Chinese Consortium
Pretends to be a Norwegian company, but is actually a Chinese company. Opera does not respect user privacy and is not trustworthy!
Con Not meant for general use
This browser is not meant for general use. It only exists, because the Opera developers had some ideas for the user-interface, and wanted their users' feedback. If you want a browser that you can use day-to-day, something with bookmarks and security updates, look elsewhere.
Con Bad UX
The usability is not the best since the left and right bar take up space and there is no way to resize them.
Con Never updated
The Opera folks came out with a browser as an experiment - and then they essentially abandoned it. It really was great, but since they never planned to support/update it and it's closed-source, it's not recommended.
Con No Adblock
There is no Adblocker like in the original Opera.
Con No extension support
Due to the way the browser is built, it does not support Chrome extensions even though it is Chromium based. Opera extensions are not supported either.
Con External Rendering Engine
It uses the Qt Web Engine from your local Qt installation which is usually not often updated.
Con No support for addons
Con Under GNU GPL
It is licensed under GPL which is less permissive than other opensource licenses like BSD or MIT.
