Just an FYI, I don't find this to be a fair statement. Firefox does this, you just don't see it. In Firefox the addons are processed within the main thread, in Chrome, they separate them out 1) to sandbox them, 2) to be able to monitor them more effectively and alert you when the plugin is misbehaving. In the end, you have a similar process by both browsers, just implemented differently and Chrome's implementation is more transparent than Firefox's.
Just wanted to clear that up.
I personally have switched to Chrome full time for a few reasons. 1) the Linux support is better than most other browsers, 2) I can sync between computers/tablets/phones easily so my bookmarks are always with me (Firefox did not have this option when I needed it), and 3) I personally like the much less cluttered look to the browser, it allows me to focus on the content and not the plugins/extensions/menu.
