What's the differences between Reborn 3 and Opera Neon (concept browser).
It seems Opera has sent it out two years ago: https://www.designernews.co/stories/78893-new-browser-opera-neon-for-mac
its seems this is the evolution of Neon, rolling all the things they learned and liked from Neon into a new browser.
"stunning", it looks nice, but I'm not stunned. A bit of an exaggeration for a browser's shell ui. ha
