Thought I ought to start a discussion, since it is now getting pretty substantial. Visually, the last few releases have vastly improved it with GTK integration and themes available from the Chrome theme site. It is also a lot more stable, and I have not had problems with basic Youtube flash playing. The most recent crash I got was exiting from the options screen, but it only happened once. :S
Your thoughts? I'm still keeping Swiftfox (Firefox) as my default, but Chrome for Linux is looking pretty neat now, although the GTK theme could do with less green.
