The Blink engine, is a good one, but we shouldn't be reliant on a single engine for most of the available browsers, especially considering who controls said engine. Of course oddly enough, Chrome wouldn't even exist if it wasn't for Safari and Safari wouldn't even exist if it wasn't for KDE. Blink(Chrome) came from Webkit(Safari) which traces it's lineage to KHTML(which was part of older versions of KDE).
