I am really happy with the AOSP browser from CM 11 or even better CM 12 (the beta one thanks to Zyan). Chrome is working lag free once it fully starts on CM 12, but when I had CM 11 or other KitKat based ROMs Chrome was a no-go. A browser to me needs to start fast and work fast, I don't care about other features such as bookmarks sync.
Chrome is garbage on gnex... Cm browser is fast, secure, and works well. I used chrome, Firefox, opera, and dolphin previously, but CM tops them all (not cyanogenmod, cheetah mobile browser from play store).
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
