If having tons of open tabs is your thing, then it really comes down to your UI preference. Firefox features a horizontal scroll on all your open tabs rather than shrinking them smaller and smaller with each new one. Google Chrome prefers to shrink them down so just the favicon is visible. The only problem with this is when you have multiple tabs open from the same website, so you see the same favicon across your tabs.
