Chrome beta is undoubtedly the best browser, or to be more honest soon to be the best browser as it evolves, but since it is still in beta it expectantly has some bugs. It does experience FCs and hang ups.
It is not just like the stock browser, it's a more unstable, though more powerful and faster version. The best feature of it is being able to sync with your desktop chrome browser. All of the history, visited links, and even tabs currently open on the PC can be accessed from it. If I visit sites on the phone, it automatically comes as a visited link on the desktop client too.
But remember it is still in beta and has some evolving to do before it's perfect.
Even with the bugs present it has replaced dolphin browser to be my new default browser.
